I had an Amiga 500 in 1993 and a year later a genuine Commodore Amiga 1200 with 2 meg of ram and Philips colour monitor, I did a lot of artwork in Deluxe Paint 4. I was amazed by Colonto's Personal Paint AGA photo image capabilities at the time, but I used Image FX 1.5 in HAM8 for doing photoshop like effects. Photogenics which came later was really next gen with natural painting effects. Maxon's Cinema 4D 2 was pretty amazing with the 3D rendered glass models that didn't take days to render. Today I use a genuine Cinema 4D R11.5XL which I spent a lot of money upgrading over the years and a bought version of Photoshop 6. The Amiga was an amazing machine with so much potential. Besides the graphics stuff, it became my main music production machine which I use with Octamed sound tracker and external midi keyboards. My Amiga 1200 lives up in the loft still to this day.
That's awesome Shyhawk! Thanks for the great comment. Deluxe Paint and ADPro were the programs I used most back then, but I am interested in doing more Photoshop like effects for a few projects I have coming up (like copying and pasting pixels - healing brush) so I will check out Image FX. So cool that you still use Cinema 4D and it started on the Amiga. I really believe the Amiga was the first home computer for artists - both visual and music. Thanks again for sharing your story with us. All the best! -- Bill
I remember back in the days putting photos underneath the DigiView camera and having to turn each of the color wheels to scan a photo into the Amiga. Kinda tedious but had some pretty good results, especially for its time. HAM mode was pretty good for colors but the resolution was not the best.
@@TheGuruMeditation Yah didn't have one of those did it all by hand but hey it was still fun do be able to do that back then. A lot of computers were not as affordable and could do a lot of digital imaging as the Amigas did. I always wish I had the Video Toaster add on but could not afford it. I loved watching the demo discs for it though.
@@robertdaone I wish i had a toaster too. Manually turning the wheel is kin of meditative though. I did enjoy that process. Makes you feel like you earned the image
Long ago I did try convert many jpegs to amiga HAM6 and HAM8 modes, and to 4-8 bps pictures with OCS and AGA palletes. After trying of couple PC image programs, viewers, converters etc, I found that Photogenics running via Winuae was best choice at all aspects.
Using Fusion or ShapeShifter mac emulation, you can run PhotoShop v3 on your Amiga. The PhotoShop IFF saver doesn't always work well and I don't recommend using it. I always preferred using ImageFX over ADPro, or even ImageMasterRT over ADPro. Beyond the basic HAM6 & HAM8 modes, you should do a follow-up episode on sliced HAM and dynamic HiRes types screenmodes that do palette changes for every screenline to give even more impressive displays.
Thanks for the comment. It would be cool to keep it an all-Amiga workflow with MAC emulation. A Dynamic hi-res follow up would be great. Right now I am editing an episode about Digi-view so stay tuned!
Great work. I remember doing stuff like this back in 95-96 in the Mac lab, transferring over psd files to iff then opening them on a friends a1200 then finally opening them on my humble a500!
Awesome Scopie! Wow, Mac lab. I had one of those at my school as well. Brings back memories. I remember studying Adobe Premiere v1.0 in that lab. Feels like yesterday! Thanks for the kind words! -- Bill
Your video has inspired me to convert my pictures made on my Olympus OM-D Em1 camera to my beloved Amiga! There's something about the graphics on the Amiga. What a great machine it was and still is. Just subscribed to your chanbel guys! Keep them coming. Greetings from the Netherlands.
AWESOME! That's the spirit Nick! The Amiga certainly has a magic that is difficult to describe, but easy to feel. You are going to have so much fun converting your photos to the various Amiga modes. Greeting from New York City! I love the Netherlands. I worked for Heineken for one year and lived in Amsterdam. It was so much fun. -- Bill
The Guru Meditation Hi! Hahaha.... HEINEKEN. I am Dutch, but don't like Heineken. Anyway, great to see that the Amiga scene is so active. How can I download that programm for the Amiga? Is there a copy of Adpro? Is it also possible to export images in Adobe Lightroom to different sizes and crop them?
NiekkieNick Ha ha, yeah I understand. As an Amirican I suppose I am supposed to like Budwiser, but I don't. Are you speaking about the GRIMM app? You can download it here GRIMM App: dspach.free.fr/amiga/grimm/ Yes you can absolute crop and export from Lightroom. That is what I do. If you want ADPro hit me up on email. my Address is BillATthegurumeditation.org. Yes, it is great to see that the Amiga is alive and well. AMIGA4EVER!!! -- Bill
I prefer German Hefe Weissbier. Really tasty! :-) Thanks for the link. I will look into that. Just bought the new ACA500+ from Individual Computers for my A500+ Does the A500 also have the HAM mode? Can't remember anymore, but I remember that the first time I saw some graphics on the A500 I was amazed how advanced the Amiga was compared to a PC at that time. Amiga had already a multitasking OS and the PC only DOS (single task OS).
NiekkieNick Oh yea, German Hefe Weissbier is awesome! I drink a lot of IPA here in New York. I love hops! The ACA500+ is great! Congrats! You will love it. Yes, the A500 does HAM mode and Dynamic hi-res. HAM mode has been available on every Amiga since the original A1000. It evolved into HAM8 AGA mode. Amiga was so far ahead of it's time when the A1000 came out. 4,096 colors on the screen at one time absolutely destroyed every other computer. I feel like it would almost be like a home computer with a holographic monitor and OS coming out today!
Artstate Digital thanks! I love ADPro. It was indespensible for me back then. I did so much work for videos and our WAUG newsletter with it. Did you see the follow up video? th-cam.com/video/_dHV_Lcbxjo/w-d-xo.html
Not had the chance as yet. I'll certainly get to it this evening. At the moment I'm just doing some research on an Amiga archive and advising them that they have incorrectly credited the programmer. It's related to a post I'll make later today.
Great video, guys! I use TV paint for my conversions but it is a bit of a memory hog. I have Adpro but never botherd learning it. Now I think I will play with it!
Thank you! I remember TV Pain, but I never used it much. I really love ADPro even though I know Image FX continued to be developed after ADPro so I know it is more advanced.. Thanks for the kind words and enjoy ADPro!
great vid guys! gave me inspiration to go find my old 3.5" disks I had on my Amiga 1000 with some gorgeous HAM pics which my Apple using friends back in the 80's couldn't produce on any Apple product back then period!
12:47 - With you guys all the way with that thought. I've known for a long time that Photo Shop can deal with IFFs, but it really sucks the immersion away from me if I have to spend all of my time on a modern machine dealing with stuff I want on the Amiga.
16:43 - The difficult part for me with transferring my pics to the Amiga is converting the often times quite strange resolutions the Amiga offered. The easiest way I've found is to just crop them all into a 4:3 resolution on a modern PC, and then resize them to say 320x200. Now 320x200 is a technical wide resolution, but always displayed on NTSC Amiga's in 4:3 - So by stretching say a 800x600 image into 320x200 what you would end up with on the Amiga is an image with the correct aspect ratio intact. If I just put say a 3:2 image or a 16:9 image and dropped it down to the 320x200 it would appear distorted on the Amiga as it forced the wide image into a 4:3 display. This is what causes me the greatest distress. I don't like dealing with the math involved in order to preserve my original photos wide aspect ratios. I believe I've done it before by letterboxing. Put the 3:2 35mm pic or 16:9 pick inside of a 800x600 canvas, and then force it into 320x200, and then it will show in the original 3:2 or 16:9 aspect when it's on the Amiga. For the most part though I've just cropped them all into 4:3 on a modern computer so I can fill up that Amiga screen and not have any distortions. I've never bothered with overscan because I haven't yet wrapped my head around the math. You did not appear to have cropped the image into 4:3 at any point, yet it showed up without distortion in 4:3 - This confuses me as I figured it would come out distorted, but it was almost like it got an automatic crop, as some of the skyline is missing on the Amiga. I'll have to play around with some overscan modes and give it a try. That final picture when dithered down looked brilliant on the Amiga! I'm usually not a fan of dithering so I didn't even try that when I was messing around with AdPro, but I can see it did an amazing job here. Great video you two!
Thanks Shot! Goto 9:54 . This is not a great example because the aspect ratio of the original image is almost identical to the aspect ratio of the Amiga's resolution, but what I do is make the longest edge of my photo fit in your target size for the Amiga. Then I extend the canvas with empty black to match the short end of the Amiga resolution. This will guarantee preserving the correct aspect ratio. I never want to crop my images when I bring them to Amiga because I am very particular about the composition and they have already been shot and cropped a very specific way. Overscan is really designed for video applications so your Amiga graphics will extend past the bezel of your CRT monitor. But, on today's flat panels you can use overscan to maximize your resolution on the Amiga side.
Great video guys. Brings back memories, though i preferred imagefx. Have you tried SHAM mode? It allows the Amiga copper to change the 16 color HAM index, reducing fringing a lot.
Thanks! Yes ImageFX is more advanced. They continued to update it after ADPro stopped being updated. No I haven't tried SHAM. Sounds cool. Thank you for the tip!
Michal Bergseth Thanks Michal! Yeah we should have done a HAM8 as well although it almost looks identical to the 24 bit. I will make one and put in in the folder I linked to in the description. thanks! -- Bill
This is one of the first things I did when I setup my Vampire... great job! I also ran Photoshop 4 on the Mac using Fusion so you can do all of it (Photoshop and AdPro) on the same Amiga.
Great vid, thanks for posting. Considering that's a 1985 system, that photo is simply amazing! (In case it's helpful to anyone, Graphic Converter on the Mac can open and save iff images.)
Hi Fellas! Love this guide, with the help of a fellow Amiga friend I've been trying this out in WinUAE! I have a MiSTer and a real A500+, but I'm experimenting with DPaint on WinUAE so that I can use a wacom tablet to draw with - it's great! One question though: I can only get this to work on the lower res settings. As soon as I go to 640x XXX, I get an ADPro error that says "The selected depth is not available on your machine". I noticed you were using an AGA Machine so I've tried several configs. This happens with A1200 and even with A4000 config... is there a setting I'm missing to get the higher res HAM modes to stick? I've not yet tried this on MiSTer AGA mode, but will shortly!
Oooohhhh...that Black Belt HAM-E box gave me flashbacks of both the delight and nightmare that HAM-E could provide. It worked really well for images but the included paint software was frustrating and terrible. I was so happy when AGA computers came out as it refined the concept and made it work seamlessly with everything, including copies of DeluxePaint that supported it from version IV onwards. If at all possible, you should cover a bit of the software that rendered to HAM mode. DigiPaint III, SpectraColor (or Photon Paint as they were basically the same software) and Electronic Arts Deluxe Photolab could do some amazing things in HAM mode, as long as you could deal with the fringing. Photolab even felt like a proto-version of Photoshop since it preceeded it and offered such advanced features as feathering edges and compositing. SpectraColor offered interesting 3D manipulations (mapping images on the side of cubes for instance) but DigiPaint III was perhaps the best as it offered many of the same features but worked in 24 bit before rendering to HAM mode, which improved the final result dramatically. Great memories and very exciting to see how well your photos rendered out to HAM mode using ADPRO. Thanks guys for another awesome show!
Oh wow, thanks for the insight Pierre! I wasn't aware that DigiPaint II worked that way. That's cool. Would love to do some videos about these pieces of software. But you are much better with the painting than either of us. Maybe we can have a special guest? :-) -- Bill
Incredibly interesting video..thx as always guys. I wish u also did a Ham8 conversion too. Curious to know how much banding and artifacts are generated relative to a true 24bit. Btw, also big thanks for the image links
Thanks for the kind words Dingo! Yeah, you are totally right, we should have done a HAM8 versions as well. Tell you what. I will do it and drop the file in the folder so at least you can see it. I'll let you know when I do it. Great idea. The HAM8 will look almost like the original 24 bit. Thanks! -- Bill
Thanks so much Quantass! Really appreciate that. We'll do more with other pieces of software we used to use back in the day. Thanks for watching! -- Bill
Love it! Gotta say, my understanding is that HAM mode was only available in low res (70ns, 320x, more with overscan) screen modes on OCS and ECS, although interlaced screens were an option. I just checked on my A600, and DPaint IV only gave me the options of 320x256 and 320x512 (both PAL, obviously). Also, while the number given for HAM8 is the same one Commodore used to give, my understanding is that HAM8 could theoretically show more than 262,144 colours, but the real limitation was that even on an overscanned super-highres laced PAL screen, you'd run out of pixels long before you'd run out of colours to display - heck even a 1920x1080 screen only has 2,073,600 pixels to display, well short of the 16,777,216 colours in the 24-bit palette (and yes, some of those would be black, so the real number is less). There is an interesting discussion about this on the EAB forum: eab.abime.net/showthread.php?t=84516
Thank Troy! Glad you like the video and thanks for the comment! Yes, I believe the max resolution of an OCS Amiga in HAM was 360x576. In retrospect perhaps I should have stuck to the original resolutions because someone else mentioned that as well, but my thinking was to use the higher resolution available on the A1200 but keep the 4,096 colors because I knew the image would be up-scaled to 1920x1080 for TH-cam so I wanted to minimize the amount of scaling. I mention that at 5:58 but perhaps I should have been more clear or just stuck with the native OCS resolutions. Oh well, it is still a fun experiment and I will see how the lower resolutions up-scale to 1920x1080. I briefly did that at VCF East and the quality was really poor a not not a good representation of what you see with your eyes on the CRT monitor even in the OCS resolutions. I will check out that thread on EAB thanks. Yes I believe you could have more then the 262,144 colors but I am not familiar with that technique. Ironically if you look at 3:52 Anthony opened the manual to the page that shows HAM8 being able to display a max of 262,144, LOL. Maybe he should play the lottery! Thanks again for watching and the link to that discussion! -- Bill
lol same. My fiance is from Lublin originally too so we go visit as often as we can. Loads of history in the city with so many amazing building. Despite being there so many times I always struggle to find any good retro games stores so if you do find any feel free to share :)
I just found this channel and loved this video. Great work guys can't wait to see more stuff! Will you be doing some software reviews for Amiga, like Fantavision, Deluxe Paint etc,
Awesome Toni! Welcome to the channel! So glad you enjoyed this. YES! We plan on doing lots of reviews of vintage Amiga hardware and software. Although, they will be more of a demo, than a review. I am editing our DigiView episode now. I should finish it in time to release it early next week!
Yes demoing software would be great, there are probably enough software reviews in old magazines. Can't wait to see those! A few years back I did one 3D illustration for Amiga community named 16 Bit Memories, it was an Amiga 500 with cannon fodder game on the screen, set during Christmas time, I would love to see that thing in HAM ... if your will ever have time to convert it. :)
Toni Bratincevic nice! Cannon Fodder is one of the all-time greats. Give me a link to it or send it to bill@thegurumeditation.org and I will work my HAM magic, ha ha
Great video guys, I really enjoyed it. Speaking of "IFF". That format was there because of the Amiga back in the days, but today is there because software like Maya uses it. Actually IFF it's native in Maya.
Ah yeah, you are totally right Mauro. I didn't show it in the video, but now that I think about it, when you save as IFF in Photoshop is asks if you are saving Amiga IFF or Maya IFF. Thanks for reminding me about this and for the great info. Cheers! -- Bill
What's also fun to know is it was EA (Electronic Arts) that created the Interchangeable File Format for their new art program for the Amiga... Deluxe Paint I wonder if you or The Guru Meditation remember that iconic box cover of a golden Tutankhamen? It was happy times 😀
You could have kept the full-on-amiga workflow and use mac classic emulation with shapeshifter and graphicconverter then transfer via mac handler too - it requires a pumped up 1200 with hard disk but is doable
Oh wow, that is a really good idea! That would be a fun project. I am hoping to keep it all Amiga for the full ADPro episode. I don't think my A1200 can handle the workflow you describe, but I am hoping to beef it up in the near future. Thanks for the cool idea Simone! -- Bill
That was part of my workflow when i used my 1200/030 as main machine - instead of graphicConverter (freeware) used a copy of photoshop 2.5 gently loaned by a friend but was doable.
The Guru Meditation Very similar to my config - just try to find the right video drivers for shapeshifter, like an older version on AGABoost like 0.1 - that should allow you to use up to 64 colors with no slowdown
Ah yeah, I probably should have. You know, I always struggle with the length of the videos. I don't want to make them too long for the average person, but someone like you who is very interested in the subject would benefit from more detail. It is a challenging balance. I decided to only show the dithering in the Lublin Sunset because the banding is more apparent in that one, but I agree it would have been nice to see both. The good news is that you can see the NYC sunset with Floyd dithering in the folder I made: goo.gl/yfOzm2 I will also make a AGA HAM8 version of the photos based on some other viewer's comments. Thanks so much for the positive feedback Ramon! All the best -- Bill
Hello! Im a bit late to this but i'd like to ask, is there a way to replicate the amiga HAM mode without having one? Ive been wondering if i could make digitized images that way for a small project of mine
@@TheGuruMeditation I tried it, and ADPro didn't seem to like that (the pics in question are from the EPCOT Legacy site, specifically the carpet pattern backgrounds). I ran them through a conversion in XNView to IFF24, and that seemed to work.
@@TheGuruMeditation currently I am finishing game written in AMOS 1.4 on Amiga 500 with 1MB RAM. Title of the game is SUPER PUZZLE, and it is computer jigsaw, where player need to create original picture from randomly set fragments. Currently in the game, are pictures that I created in Deluxe Paint 4 in 1999. These are silouethes of Disney cartoons: Pluto and Simba from The Lion King. I dont have any rights to use this graphics, so I decided to change this pictures to photos of my pupils: a Cocker Spaniel, Cat and Guinea Pigs. All I need to do is to transfer photos from JPEG format, into Amiga 500 Half-and-Modify (320x240px with 4096 colors) IFF files, and then ... transfer those IFF to one ADF file which will be open from WinUAE level and readable by Deluxe Paint and AMOS 1.4. I will be very gratefull if You will help me in this effort I will discover some difficulties. Greetings from Kalisz, Poland!
I am not sure. I am not familiar with the Atari 800's graphic capabilities but it is something I should learn - especially for out upcoming Jay Miner tribute exhibit at VCF East!
@@jrherita I can talk to Joe Decuir about it directly as he will be part of out Atari 40th/Jay Miner tribute exhibit at VCF East this year! twitter.com/TheGuruMeditate/status/1108715132492922881
I use Kodak PhotoCD image in '90 year' s for ImageFX, Amazing Amiga 1200 030, for printer Canon photo high quality and big photos Jet print. Fantastic remember 80-90-2000's year work on Amiga classic. Now i love my AmigaOS4. X sistem fast. 😃
Awesome! Love the nostalgia CelentAle. I never printed my photos much, but I did have a lot of friends with Canon printers. I haven't jumped into OS4 yet, but it is on my to-do list. Thanks for watching! -- Bill
Another awesome videos guys! Now my fingers are tickling and i want to repeat your technique on my real 1200. :) I am also considering using Personal Paint and Deluxe Paint to compare the results with ADPro.
Nice Alex! Do it! The is nothing like using the real machine. I have WINUAE and FS-UAE and they are both great, but there is nothing like the real thing! A comparison would be cool. Although, I don't believe DPain can read JPGs and convert them to IFF, but I haven't tried that in decades. I used to convert with ADPro. All the best! -- Bill
By the way, Digital Creations' DCTV (which came with the fantastic DCTV Paint) used an even more clever method of storing 21 bits of video data into 4 or 6 bits. You could even render DCTV animations that played at 30 fps or more (since the Amiga just treated it like a normal display mode). Very very cool. Wish I still had mine! JW3HH
Yep, I love DCTV. I used it all the time. It was my goto. However I never tried doing video with it. That will be a great project. I used DCTV for part of our Amiga exhibit at this year's VCF. You can see it in action here: th-cam.com/video/HEIesAtmKfM/w-d-xo.html Thanks for the great comments! -- Bill
Yeah, in the days before the internet I somehow came across an Anim-5 video (remember those?) that was to be played on a DCTV. I don't remember what it was (I think it was a clip from one of Pixar's early shorts like "Red's Dream"), but it looked AMAZING, especially for the time. Yeah, DCTV was an awesome piece of hardware and DCTV Paint was actually a very capable paint program as well. JW3HH p.s. Have you guys ever tried/reviewed the MiST FPGA Amiga/Atari ST system?
oh yeah, Anim-5. That brings back memories! wow. I have to get some video cooking on my DCTV. No, we haven't got our hands on a MiST FPGA yet, but it looks really awesome.
Thanks Stigs! I wanted to do this video because of the technical issues on the live stream. Fortunately I have learned from my mistakes and I have a better handle on the live streaming now. Let me know if you want any more conversions done! -- Bill
what version of adpro are you using there and is it avalible for free, my version is some old one with a huge gfx gui interface, not system gui interface like yours
Great question. The version with the GUI that you know of is the original. This is version 2.5 which is the last version. They re-designed the interface. Technically it isn't available, but it is out there if you know the right channels. If you send me an email I can point you there BillATthegurumeditationDOTorg
HOW do they do it????? WHY do they do it???? hahahahah. old musician joke. great video, as always. I'm gonna have to try this. Baby needs a new FB profile pic, you dig.
You are welcome, I have been teaching people how to use PhotoShop for about 20 years now for an adult continuing education center connected to The University of Missouri St. Louis. I have been enjoying your youtube vids and missing my 5 Amigas that I once had.
Oh neat! Good for you. I love Photoshop. The more I learn about it, the more I realize I don't know. I do cinematography for a living, and occasionally shoot some stills as well so I have a basic feel for it, but it can do so much I feel like I have only scratched the surface. It is an incredible tool especially when put into the right hands! Thanks so much for watching our channel and the kind words. Really appreciate that and am glad you are enjoying it. We have some really exciting stuff on the horizon - especially when it comes to photography and video on the Amiga. We are just getting warmed up! All the best, Bill
here at raw.githubusercontent.com/nitrofurano/luascripts/master/scripts/gluas/amigaham.lua i have a gimp-gluas script that aims to get closer to a ham6 conversion result (i only used those “primary distortion” colours 16..63 - i still have no idea how to better quantize the best 16 indexed colours )
***** Post them up! I want to see. I would love to know your workflow on that. I would love to create some HAM video of my own, but I might stick to HAM6, LOL!
***** Damn I have a lot of your videos to catch up on! I wish there was a better way of knowing when friends post a new video. Sort of like a News Feed on Facebook. TH-cam's interface is really designed for video searching, vs watching your friend's latest videos. I have to be sure to check that left side bare often, but even then I miss plenty of videos. Can't wait to see the series on Amiga disk copy software! Cool!
When I first saw the DigiView pictures I was already used to 24bit images so I thought they were garbage and I thought it was just a toy computer trying to punch above its weight. I am even more convinced of that now I know those HAM6 images are basically useless. Also: Typical of Amiga fans a lot of this "Unlike on other computers" comes from people who clearly don't know how other computers work: The three letter file extension talk is garbage. The three letter file extension serves as nothing but an organising label for file managers. In most even remotely well written apps they use the header contents for validation testing, not the three letter extension. "I had a Mimetics frame bufffer which allowed for /basically/ 24bit images to be displayed". Which Mimetics frame buffer? Is there more than one? The only Mimetics frame buffer I know of can only display 21bit colour. That's what you mean by "basically" 24bit, isn't it? What you mean by "which allowed for /basically/ 24bit images to be displayed" is "but it did not allow 24bit images to be displayed". Go on, Amiga fan base, start telling the truth for the first time in your lives. "A 320x200 getting blown up to 1920x080 which this video is gong to be in is really going to give you a massive amount of artefacts". Yeah.... in other words, what it is going to do is reveal what HAM6 *really* looked like and you don't want other people to have the same disappointing experience I had so you're showing what could NOT be done on an Amiga for the first 7 years of its life, and by the time it could do what you're showing there were plenty of better graphics cards for the PC. "I'm going to use a Mac...", because even the Amiga fan accepts they'd be a fool to try picture editing for the Amiga actually using the Amiga, this alleged graphics superpower. "That's a hard image for HAM...". No it isn't. It's mostly smooth graduations of almost primary colours. It's approaching the easiest kind of picture for HAM to emulate. What you want for a real test is a very noisy reference image with lots of very different colours grouped as closely together as possible in the x direction. That's what HAM can't do: High density colour images.
The wikipedia description of HAM mode goes like this: &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& HAM6 encoding uses six bits per pixel: two bits for control and four bits for data. If the two control bits are both set to zero, the four remaining bits are used to index one of the 16 preset color registers, operating in the fashion of a normal indexed bitmap. The other three possible control bit patterns indicate that the color of the previous pixel (to the left) on the scanline should be used and the data bits should instead be used to modify the value of the red, green or blue component. Consequently, there are four possibilities: Set: Use the 4 bits of data to index a color from the 16 color palette. Use that color for this pixel. Modify Red: Hold the green and blue color components of the previous pixel. Use the 4 bits of data as the new red color component of this pixel. Modify Green: Hold the red and blue color components of the previous pixel. Use the 4 bits of data as the new green color component of this pixel. Modify Blue: Hold the red and green color components of the previous pixel. Use the 4 bits of data as the new blue color component of this pixel. &&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&& There was also a HAM8 mode on AGA Amigas and a third party HAM-E by Blackbelt Systems that was similar to HAM8, but at low resolution (AGA HAM8 can use any horizontal resolution, including 1280). Another variation was "sliced HAM" (you can't make this stuff up...) or SHAM, where the palette could be changed on every vertical line. This added more freedom to where you could put colors, but was more system hungry. I remember being blown away by pictures displayed in this mode. HAM8 made this mode obsolete. The "fringing" you speak of can be greatly reduced or even eliminated with very careful palette selection and pixel data. (There were programs back then that could analyze your HAM image and reorganize it for this purpose). JW3HH
Yep exactly. We read the Wikipedia entry many times, but decided not to get too technical with the video. It is a great read though and a good idea to post it here. Thanks! We also did a follow up to this episode. I am editing it now and it will be posted next week so stay tuned! -- Bill
Ah yes, I love my DCTV!!!! Sorry for the late response. It was filed under "Likely SPAM" Silly Google. Thanks so much for all the great info. Much appreciated dude. We will do a DCTV episode as well. I used it at the Vintage Computer Festival last year. Oh, and I just finished a follow up to this video. Thanks again JW3HH! th-cam.com/video/_dHV_Lcbxjo/w-d-xo.html
Cool! I'll check it out! I think it's so great that retrocomputing has become so popular in the last few years: New games, new hardware, shows in all parts of the world devoted to those old computers and so on (And not just the Amiga, either. Commodore 64, Sinclair Spectrum, Atari STs and so on have lots of support from their devoted fans. Some of the FPGA hardware out there is really fascinating (and not that expensive, either!), including a 200+ mhz 68060 accelerator for the A600 (I think it's called Vampire). It's very exciting! Some group is even "rebooting" the C64 with higher quality video (HDMI and/or S-Video), sound and so on. They even licensed the official Commodore ROMs, etc. Nice! JW3HH
Why extend the canvas by one pixel rather than just rescale the image to the 724? Did you also save as lossless JPEG because otherwise you are added additional artefacts into the image which the HAM mode has to render.
Hey James! Thanks for watching and the comment. I extended the canvas because if I made the width of the image 724 then the height would be 483 which would exceeded the maximum resolution of 482. Again, one line of resolution is probably imperceptible, but with an image of a different aspect ratio I would want to keep the 482 to maximize my resolution because I still have a lot more resolution in the width to play with. For example, if the image was 16:9 aspect ratio and I set the width to 724 then my height would be 407 and I wouldn't have the max resolution available to me. Instead I would set the height to 482 (the max) and my width would be 857 which fits in Super-High Res Laced Extreme Size 1448x482. When I made the JPG I set it to the lowest compression of 12. Is there such a thing as an uncompressed JPG? I never heard of that. I make uncompressed TIFF and PNG files all the time from my Camera RAW files, but I never heard of an uncompressed JPG. Thanks again for watching and commenting. I hope I was able to explain the method of my madness! Best, -- Bill
I would just rescale it to 482x724, for one pixel the change in aspect ratio would not be noticeable. Yes other lossless formats such PNG or TIFF would be more a better choice.
Neat. Thanks for the info about Lossless. I doubt ADPro can accept an image with that compression, but worth a try. It also doesn't have a loader for TIFF or PNG so I am not sure if it can bring those in. I'll have to give it a try. Although one could argue that regular JPG at 12 (Max) compression is pretty darn good.
Easy to follow! Here is what happens if you use Photoshop and then Personal Paint 7.2! priness-lady-nicola.deviantart.com/art/HAM-Mode-Amiga-A1200-709139932
Hi Guys. Its hard for me to write this because you are doing the great job, but i had to say it because your inaccuracy could mess in people head. Original Amiga chipset OCS, could display HAM mode only in Low resolution 320 (352 overscan) while the vertical could be 512 in PAL(or 576 overscan) or 400 in NTSC. You have used HAM6 mode on AGA so while you could display 640x480 HAM6 image in reality NOBODY would be interested in using that mode if for 2 bitplanes more you could actually have so much more . This makes the whole video purelly artificial and could convince newbie that amiga actually could do something which in reality it cant. Conversion to HAM6 mode is actually very difficult proces, because first you need to convert resolution to 320x480 then convert RGB24 to RGB12 then apply HAM compression. Each of those steps makes a difference and if you would do it wrongly the final effect will not be as good as it could be. It is also worth to mension that in low resolution mode the noise caused by dithering is much more visible making the whole process even more difficult and FS is not a best option here. Me and my friend are researching this topic in order to create the best ham converter (and recently also Dynamic Hires) and i can tell you it is very difficult. We also started to research Dynamic Hires which in fact allows you to display 640x480 picture on standard OCS machine and i posted some pictures here .www.imagebam.com/image/e4e1b9516025848 In Dynamic Hires picture contains 504 colours (843 in lowres HAM6) but only 16 in each line, while Lublin has 263 (725 in lowres HAM6) and also only 16 in each line. However you can see that Dynamic Hires blows away HAM6 picture thanx to higher resolution.
Hi Trachu. Thanks for the comment and the kind words. Yes I am aware that OCS does HAM in up to 360x576. In retrospect I probably should have stuck to those resolutions, but if you watch the video at 5:58 I explain that I am cheating and using higher resolutions because of the 1920x1080 upscale and conversion to mp4. I did have Dynamic HiRes in mind when doing this because I used to use that mode with DigiView all the time. I will never forget NewTek Demo Reel 3 with this announcement and image: th-cam.com/video/DybXc-WEf6Y/w-d-xo.htmlm49s My thinking was to use the higher resolution available on the A1200 but keep the 4,096 colors because I knew the image would be up-scaled to 1920x1080 for TH-cam so I wanted to minimize the amount of scaling. I briefly upscaled low-res OCS images to higher resolutions at VCF East and the quality looked poor on modern equipment and I felt that it wasn't a good representation of what you see with your eyes on the CRT monitor even in the OCS resolutions on a real Amiga. I certainly didn't mean to mislead anyone. Perhaps it wasn't the right decision, but I thought it was the best option at the time. It is still 4,096 colors which was my main goal. I will have to go back and experiment with the lower resolutions and see how they look when upscaled to 1920x1080 with mp4 codec. Good luck with your software. It sounds great and thanks for experimenting with the images. That is very cool. Please keep me posted with your progress. My one suggestion is that your software must maintain the original aspect ratio of the image regardless of Amiga screen resolutions. Otherwise it world force the photographer to use additional software and mental calculations to correct the aspect ratio. Obviously distorted images like the 2 you presented in that gallery are not acceptable even though that was a technical demonstration. Thanks again for taking the time to experiment with the images and providing some insight. -- Bill
352x576 not 360 - Amiga splits horizontal display into 16px chunks, so while you can set any resolution inbetween it will allocate DMA needed to feed nearest mod16 resolution. As for your conversion process, my point is that RGB24to12 conversion done in Lowres is much more difficult because applying nice looking dithering to Lowres is much harder than in Highres. Good portion of your video is praising dithering as the tool to make the banding go away. It is not as easy as you have described it. Basically what you have done is purelly theorethic. In AGA we have HAM8 which when done correctly can display pictures indistingishibles from originals. In terms of aspect ratio - I have included original files (just like you did) so anyone can take them and try to use other display programms to receive ham picture. Turning on interlace make the picture thinner, but it would display correctly on Amiga, that is why HAM6 output is doubled horizontally to mimic how it would look on real Amiga. If you want to see more Dynamic Hires pictures heres another link www.imagebam.com/image/26443f511709489
Yeah, in retrospect I should have just done it in Low Res, but I was concerned about the upscale to 1920x1080. I felt like a low res HAM mage upscaled to higher resolutions on a modern computer look worse than the same low resolution image on a CRT (I am talking about what is perceived by your eye), but I will experiment more with that. I should have just used 320x200 which is what I mostly did back then except for dynamic hi-res. So much for my modern twist, LOL. You should offer the correct max resolution to Wikipedia because it says 360x576 is max for HAM6, but maybe that is ECS?
Again, I totally feel you with the 24 to 12 bit conversion and dithering in low res, but I was trying to avoid the 5.4x scale to 1080 and all the side effects that come with that and minimize it to 2.2x upscale. I probably should have made low res images for the folder and used the workflow in the video to present the image on TH-cam. But either way converting to 1920x1080 mp4 is a bastardization of the original image anyway. But now you have me wrestling with my decision, lol! Let me know when you have your software up and running. I would love to play with it.
Brought back fond memories.
Fantastic! That is exactly the mission of our videos! Enjoy
There are demos that show off HAM8 in real-time animations, and it is jaw-dropping - "Tint" by The Black Lotus is probably the most famous example.
Cool. I will look that one up. Thanks
I am 100% behind you guys continuing to share stuff like this. Really love the vintage optics.
Thanks Rocky! I have some really cool projects planned using the Amiga and vintage equipment so stay tuned for more! -- Bill
I had an Amiga 500 in 1993 and a year later a genuine Commodore Amiga 1200 with 2 meg of ram and Philips colour monitor, I did a lot of artwork in Deluxe Paint 4. I was amazed by Colonto's Personal Paint AGA photo image capabilities at the time, but I used Image FX 1.5 in HAM8 for doing photoshop like effects. Photogenics which came later was really next gen with natural painting effects. Maxon's Cinema 4D 2 was pretty amazing with the 3D rendered glass models that didn't take days to render. Today I use a genuine Cinema 4D R11.5XL which I spent a lot of money upgrading over the years and a bought version of Photoshop 6. The Amiga was an amazing machine with so much potential. Besides the graphics stuff, it became my main music production machine which I use with Octamed sound tracker and external midi keyboards. My Amiga 1200 lives up in the loft still to this day.
That's awesome Shyhawk! Thanks for the great comment. Deluxe Paint and ADPro were the programs I used most back then, but I am interested in doing more Photoshop like effects for a few projects I have coming up (like copying and pasting pixels - healing brush) so I will check out Image FX. So cool that you still use Cinema 4D and it started on the Amiga. I really believe the Amiga was the first home computer for artists - both visual and music. Thanks again for sharing your story with us. All the best! -- Bill
Love this video - keep up the good work fellas !
Thanks so much MVG! I have to catch up on your videos as well. Love your work! -- Bill
I remember back in the days putting photos underneath the DigiView camera and having to turn each of the color wheels to scan a photo into the Amiga. Kinda tedious but had some pretty good results, especially for its time. HAM mode was pretty good for colors but the resolution was not the best.
Oh yeah those were great times. We actually did a DigiView video, but I was using the DigiDroid to turn the color wheel.
@@TheGuruMeditation Yah didn't have one of those did it all by hand but hey it was still fun do be able to do that back then. A lot of computers were not as affordable and could do a lot of digital imaging as the Amigas did. I always wish I had the Video Toaster add on but could not afford it. I loved watching the demo discs for it though.
@@robertdaone I wish i had a toaster too. Manually turning the wheel is kin of meditative though. I did enjoy that process. Makes you feel like you earned the image
Long ago I did try convert many jpegs to amiga HAM6 and HAM8 modes, and to 4-8 bps pictures with OCS and AGA palletes. After trying of couple PC image programs, viewers, converters etc, I found that Photogenics running via Winuae was best choice at all aspects.
Hummm I never used Photogenics. I will check it out. Thanks for the tip! -- Bill
Using Fusion or ShapeShifter mac emulation, you can run PhotoShop v3 on your Amiga. The PhotoShop IFF saver doesn't always work well and I don't recommend using it. I always preferred using ImageFX over ADPro, or even ImageMasterRT over ADPro.
Beyond the basic HAM6 & HAM8 modes, you should do a follow-up episode on sliced HAM and dynamic HiRes types screenmodes that do palette changes for every screenline to give even more impressive displays.
Thanks for the comment. It would be cool to keep it an all-Amiga workflow with MAC emulation. A Dynamic hi-res follow up would be great. Right now I am editing an episode about Digi-view so stay tuned!
Great work. I remember doing stuff like this back in 95-96 in the Mac lab, transferring over psd files to iff then opening them on a friends a1200 then finally opening them on my humble a500!
Awesome Scopie! Wow, Mac lab. I had one of those at my school as well. Brings back memories. I remember studying Adobe Premiere v1.0 in that lab. Feels like yesterday! Thanks for the kind words! -- Bill
Your video has inspired me to convert my pictures made on my Olympus OM-D Em1 camera to my beloved Amiga! There's something about the graphics on the Amiga. What a great machine it was and still is. Just subscribed to your chanbel guys! Keep them coming. Greetings from the Netherlands.
AWESOME! That's the spirit Nick! The Amiga certainly has a magic that is difficult to describe, but easy to feel. You are going to have so much fun converting your photos to the various Amiga modes. Greeting from New York City! I love the Netherlands. I worked for Heineken for one year and lived in Amsterdam. It was so much fun. -- Bill
The Guru Meditation Hi! Hahaha.... HEINEKEN. I am Dutch, but don't like Heineken. Anyway, great to see that the Amiga scene is so active. How can I download that programm for the Amiga? Is there a copy of Adpro? Is it also possible to export images in Adobe Lightroom to different sizes and crop them?
NiekkieNick
Ha ha, yeah I understand. As an Amirican I suppose I am supposed to like Budwiser, but I don't. Are you speaking about the GRIMM app? You can download it here GRIMM App: dspach.free.fr/amiga/grimm/ Yes you can absolute crop and export from Lightroom. That is what I do. If you want ADPro hit me up on email. my Address is BillATthegurumeditation.org. Yes, it is great to see that the Amiga is alive and well. AMIGA4EVER!!! -- Bill
I prefer German Hefe Weissbier. Really tasty! :-) Thanks for the link. I will look into that. Just bought the new ACA500+ from Individual Computers for my A500+ Does the A500 also have the HAM mode? Can't remember anymore, but I remember that the first time I saw some graphics on the A500 I was amazed how advanced the Amiga was compared to a PC at that time. Amiga had already a multitasking OS and the PC only DOS (single task OS).
NiekkieNick
Oh yea, German Hefe Weissbier is awesome! I drink a lot of IPA here in New York. I love hops! The ACA500+ is great! Congrats! You will love it. Yes, the A500 does HAM mode and Dynamic hi-res. HAM mode has been available on every Amiga since the original A1000. It evolved into HAM8 AGA mode. Amiga was so far ahead of it's time when the A1000 came out. 4,096 colors on the screen at one time absolutely destroyed every other computer. I feel like it would almost be like a home computer with a holographic monitor and OS coming out today!
Great results with the final image and Floyd dithering applied. Nice to see that rare hardware, too.
Artstate Digital thanks! I love ADPro. It was indespensible for me back then. I did so much work for videos and our WAUG newsletter with it. Did you see the follow up video? th-cam.com/video/_dHV_Lcbxjo/w-d-xo.html
Not had the chance as yet. I'll certainly get to it this evening. At the moment I'm just doing some research on an Amiga archive and advising them that they have incorrectly credited the programmer. It's related to a post I'll make later today.
No rush! Just wanted to alert you to it. Go set 'em straight!
Ad Pro! Wow what a trip down memo lane. A3000 with an Opalvison card and Emplant mac emulator started my whole career. Cheers for this vid
Oh nice Tim! Appreciate this comment very much. Thank you!
Great video, guys! I use TV paint for my conversions but it is a bit of a memory hog. I have Adpro but never botherd learning it. Now I think I will play with it!
Thank you! I remember TV Pain, but I never used it much. I really love ADPro even though I know Image FX continued to be developed after ADPro so I know it is more advanced.. Thanks for the kind words and enjoy ADPro!
I had several Amiga models and did also transfer JPGs from the PC to the Amiga.
Cool! It is a fun process. Thanks Alexander! -- Bill
great vid guys! gave me inspiration to go find my old 3.5" disks I had on my Amiga 1000 with some gorgeous HAM pics which my Apple using friends back in the 80's couldn't produce on any Apple product back then period!
Nice f1lupo! That's awesome. Gotta preserve that classic stuff
12:47 - With you guys all the way with that thought. I've known for a long time that Photo Shop can deal with IFFs, but it really sucks the immersion away from me if I have to spend all of my time on a modern machine dealing with stuff I want on the Amiga.
16:43 - The difficult part for me with transferring my pics to the Amiga is converting the often times quite strange resolutions the Amiga offered. The easiest way I've found is to just crop them all into a 4:3 resolution on a modern PC, and then resize them to say 320x200. Now 320x200 is a technical wide resolution, but always displayed on NTSC Amiga's in 4:3 - So by stretching say a 800x600 image into 320x200 what you would end up with on the Amiga is an image with the correct aspect ratio intact.
If I just put say a 3:2 image or a 16:9 image and dropped it down to the 320x200 it would appear distorted on the Amiga as it forced the wide image into a 4:3 display. This is what causes me the greatest distress. I don't like dealing with the math involved in order to preserve my original photos wide aspect ratios. I believe I've done it before by letterboxing. Put the 3:2 35mm pic or 16:9 pick inside of a 800x600 canvas, and then force it into 320x200, and then it will show in the original 3:2 or 16:9 aspect when it's on the Amiga. For the most part though I've just cropped them all into 4:3 on a modern computer so I can fill up that Amiga screen and not have any distortions.
I've never bothered with overscan because I haven't yet wrapped my head around the math. You did not appear to have cropped the image into 4:3 at any point, yet it showed up without distortion in 4:3 - This confuses me as I figured it would come out distorted, but it was almost like it got an automatic crop, as some of the skyline is missing on the Amiga. I'll have to play around with some overscan modes and give it a try. That final picture when dithered down looked brilliant on the Amiga! I'm usually not a fan of dithering so I didn't even try that when I was messing around with AdPro, but I can see it did an amazing job here. Great video you two!
Thanks Shot! Goto 9:54 . This is not a great example because the aspect ratio of the original image is almost identical to the aspect ratio of the Amiga's resolution, but what I do is make the longest edge of my photo fit in your target size for the Amiga. Then I extend the canvas with empty black to match the short end of the Amiga resolution. This will guarantee preserving the correct aspect ratio. I never want to crop my images when I bring them to Amiga because I am very particular about the composition and they have already been shot and cropped a very specific way. Overscan is really designed for video applications so your Amiga graphics will extend past the bezel of your CRT monitor. But, on today's flat panels you can use overscan to maximize your resolution on the Amiga side.
this is a great tutorial and explanation. I now know more about HAM modes. Thank you for sharing guys.
Thank you so much Pedro! So glad you got something out of the video. We dis a follow up to this one here: th-cam.com/video/_dHV_Lcbxjo/w-d-xo.html
Yes Gurus I know... I'm watching all you videos! great info from a great team! keep pouring that Amiga passion boys.
Thank you Pedro! I am editing a new video right now! -- Bill
Great video guys. Brings back memories, though i preferred imagefx. Have you tried SHAM mode? It allows the Amiga copper to change the 16 color HAM index, reducing fringing a lot.
Thanks! Yes ImageFX is more advanced. They continued to update it after ADPro stopped being updated. No I haven't tried SHAM. Sounds cool. Thank you for the tip!
Nice video guys, the guru's are at there best again!! Keep up the great work!!
Aw, thanks my man! You rock dude! -- Bill
Very nice show indeed! HAM8, now that would be interesting to show. Keep up the good work!
Michal Bergseth Thanks Michal! Yeah we should have done a HAM8 as well although it almost looks identical to the 24 bit. I will make one and put in in the folder I linked to in the description. thanks! -- Bill
This is one of the first things I did when I setup my Vampire... great job! I also ran Photoshop 4 on the Mac using Fusion so you can do all of it (Photoshop and AdPro) on the same Amiga.
Sweet! That has to be my next step - doing everything on Amiga hardware only. -- Bill
There are Denise and Agnus replacement projects to bring AGA for OCS/ECS-equipped Amigas. HAM-E is not register compatible with AGA.
Great vid, thanks for posting. Considering that's a 1985 system, that photo is simply amazing! (In case it's helpful to anyone, Graphic Converter on the Mac can open and save iff images.)
Aw thanks so much. I really appreciate it and will check out Graphic Converter. Thanks!
you could also work in multiples of the amiga format image dimensions ,and just crop the image to those numbers then scale.
Great informative and very well presented videos. Keep up the awesome work. Im a subscriber for life!
Aw, thank you! We don't make a lot of videos, but we will keep making them for the rest of our lives so stay tuned!
Hi Fellas! Love this guide, with the help of a fellow Amiga friend I've been trying this out in WinUAE!
I have a MiSTer and a real A500+, but I'm experimenting with DPaint on WinUAE so that I can use a wacom tablet to draw with - it's great!
One question though: I can only get this to work on the lower res settings. As soon as I go to 640x XXX, I get an ADPro error that says "The selected depth is not available on your machine". I noticed you were using an AGA Machine so I've tried several configs.
This happens with A1200 and even with A4000 config... is there a setting I'm missing to get the higher res HAM modes to stick? I've not yet tried this on MiSTer AGA mode, but will shortly!
Oooohhhh...that Black Belt HAM-E box gave me flashbacks of both the delight and nightmare that HAM-E could provide. It worked really well for images but the included paint software was frustrating and terrible. I was so happy when AGA computers came out as it refined the concept and made it work seamlessly with everything, including copies of DeluxePaint that supported it from version IV onwards.
If at all possible, you should cover a bit of the software that rendered to HAM mode. DigiPaint III, SpectraColor (or Photon Paint as they were basically the same software) and Electronic Arts Deluxe Photolab could do some amazing things in HAM mode, as long as you could deal with the fringing. Photolab even felt like a proto-version of Photoshop since it preceeded it and offered such advanced features as feathering edges and compositing. SpectraColor offered interesting 3D manipulations (mapping images on the side of cubes for instance) but DigiPaint III was perhaps the best as it offered many of the same features but worked in 24 bit before rendering to HAM mode, which improved the final result dramatically.
Great memories and very exciting to see how well your photos rendered out to HAM mode using ADPRO. Thanks guys for another awesome show!
Oh wow, thanks for the insight Pierre! I wasn't aware that DigiPaint II worked that way. That's cool. Would love to do some videos about these pieces of software. But you are much better with the painting than either of us. Maybe we can have a special guest? :-) -- Bill
Incredibly interesting video..thx as always guys.
I wish u also did a Ham8 conversion too. Curious to know how much banding and artifacts are generated relative to a true 24bit.
Btw, also big thanks for the image links
Thanks for the kind words Dingo! Yeah, you are totally right, we should have done a HAM8 versions as well. Tell you what. I will do it and drop the file in the folder so at least you can see it. I'll let you know when I do it. Great idea. The HAM8 will look almost like the original 24 bit. Thanks! -- Bill
Dingoooooo!!!! Thanks for the comment. We did a HAM8 conversion for you in our latest video. Check it: th-cam.com/video/_dHV_Lcbxjo/w-d-xo.html
That was a terrific video. Well explained from beginning to end.
Thanks so much Quantass! Really appreciate that. We'll do more with other pieces of software we used to use back in the day. Thanks for watching! -- Bill
Love it! Gotta say, my understanding is that HAM mode was only available in low res (70ns, 320x, more with overscan) screen modes on OCS and ECS, although interlaced screens were an option. I just checked on my A600, and DPaint IV only gave me the options of 320x256 and 320x512 (both PAL, obviously).
Also, while the number given for HAM8 is the same one Commodore used to give, my understanding is that HAM8 could theoretically show more than 262,144 colours, but the real limitation was that even on an overscanned super-highres laced PAL screen, you'd run out of pixels long before you'd run out of colours to display - heck even a 1920x1080 screen only has 2,073,600 pixels to display, well short of the 16,777,216 colours in the 24-bit palette (and yes, some of those would be black, so the real number is less). There is an interesting discussion about this on the EAB forum: eab.abime.net/showthread.php?t=84516
Thank Troy! Glad you like the video and thanks for the comment! Yes, I believe the max resolution of an OCS Amiga in HAM was 360x576. In retrospect perhaps I should have stuck to the original resolutions because someone else mentioned that as well, but my thinking was to use the higher resolution available on the A1200 but keep the 4,096 colors because I knew the image would be up-scaled to 1920x1080 for TH-cam so I wanted to minimize the amount of scaling. I mention that at 5:58 but perhaps I should have been more clear or just stuck with the native OCS resolutions. Oh well, it is still a fun experiment and I will see how the lower resolutions up-scale to 1920x1080. I briefly did that at VCF East and the quality was really poor a not not a good representation of what you see with your eyes on the CRT monitor even in the OCS resolutions. I will check out that thread on EAB thanks. Yes I believe you could have more then the 262,144 colors but I am not familiar with that technique. Ironically if you look at 3:52 Anthony opened the manual to the page that shows HAM8 being able to display a max of 262,144, LOL. Maybe he should play the lottery! Thanks again for watching and the link to that discussion! -- Bill
Hey Troy, thanks for the comment! It inspired us to make a follow up video. Check it out: th-cam.com/video/_dHV_Lcbxjo/w-d-xo.html
Great video. Was odd to see the Lublin photo as was stood exactly there only days ago. Small world
ha ha, nice! My wife was born and raised in Lublin. We go there every year to visit her family. I love that city.
lol same. My fiance is from Lublin originally too so we go visit as often as we can. Loads of history in the city with so many amazing building. Despite being there so many times I always struggle to find any good retro games stores so if you do find any feel free to share :)
The best retro games there are about 45 minutes away in Chelm - at AmiParty! Lublin does have amazing ice cream though!
Just wow, Learnt something new today! Thanks guys
Fantastic! Thanks for the kind comment and glad you got something from our shenanigans ! -- Bill
I just found this channel and loved this video. Great work guys can't wait to see more stuff! Will you be doing some software reviews for Amiga, like Fantavision, Deluxe Paint etc,
Awesome Toni! Welcome to the channel! So glad you enjoyed this. YES! We plan on doing lots of reviews of vintage Amiga hardware and software. Although, they will be more of a demo, than a review. I am editing our DigiView episode now. I should finish it in time to release it early next week!
Yes demoing software would be great, there are probably enough software reviews in old magazines. Can't wait to see those! A few years back I did one 3D illustration for Amiga community named 16 Bit Memories, it was an Amiga 500 with cannon fodder game on the screen, set during Christmas time, I would love to see that thing in HAM ... if your will ever have time to convert it. :)
Toni Bratincevic nice! Cannon Fodder is one of the all-time greats. Give me a link to it or send it to bill@thegurumeditation.org and I will work my HAM magic, ha ha
Thank you! Cannon fodder was great, spend a lot of time playing it. Such a fun game, Here is the link www.artstation.com/artwork/LRwk
Great video guys, I really enjoyed it.
Speaking of "IFF". That format was there because of the Amiga back in the days, but today is there because software like Maya uses it. Actually IFF it's native in Maya.
Ah yeah, you are totally right Mauro. I didn't show it in the video, but now that I think about it, when you save as IFF in Photoshop is asks if you are saving Amiga IFF or Maya IFF. Thanks for reminding me about this and for the great info. Cheers! -- Bill
What's also fun to know is it was EA (Electronic Arts) that created the Interchangeable File Format for their new art program for the Amiga... Deluxe Paint
I wonder if you or The Guru Meditation remember that iconic box cover of a golden Tutankhamen?
It was happy times 😀
@@devilsadvocate1597
Well, how could I not remember that? Especially given it was made by hand, not digitized. :-)
You could have kept the full-on-amiga workflow and use mac classic emulation with shapeshifter and graphicconverter then transfer via mac handler too - it requires a pumped up 1200 with hard disk but is doable
Oh wow, that is a really good idea! That would be a fun project. I am hoping to keep it all Amiga for the full ADPro episode. I don't think my A1200 can handle the workflow you describe, but I am hoping to beef it up in the near future. Thanks for the cool idea Simone! -- Bill
That was part of my workflow when i used my 1200/030 as main machine - instead of graphicConverter (freeware) used a copy of photoshop 2.5 gently loaned by a friend but was doable.
Simone Bernacchia That's awesome. My 1200 is an 030 with 16mb RAM so perhaps I can give it a go
The Guru Meditation Very similar to my config - just try to find the right video drivers for shapeshifter, like an older version on AGABoost like 0.1 - that should allow you to use up to 64 colors with no slowdown
Simone Bernacchia
Cool, thanks again Simone!
nice vid! You should have applied dithering on the New York skyline image too.
Ah yeah, I probably should have. You know, I always struggle with the length of the videos. I don't want to make them too long for the average person, but someone like you who is very interested in the subject would benefit from more detail. It is a challenging balance. I decided to only show the dithering in the Lublin Sunset because the banding is more apparent in that one, but I agree it would have been nice to see both. The good news is that you can see the NYC sunset with Floyd dithering in the folder I made: goo.gl/yfOzm2 I will also make a AGA HAM8 version of the photos based on some other viewer's comments. Thanks so much for the positive feedback Ramon! All the best -- Bill
Hello! Im a bit late to this but i'd like to ask, is there a way to replicate the amiga HAM mode without having one? Ive been wondering if i could make digitized images that way for a small project of mine
What would you suggest for someone who doesn't have Photoshop, and only has a bunch of PNG files?
Great question. Try GIMP and save your PNG's as JPGs
@@TheGuruMeditation I tried it, and ADPro didn't seem to like that (the pics in question are from the EPCOT Legacy site, specifically the carpet pattern backgrounds). I ran them through a conversion in XNView to IFF24, and that seemed to work.
Very interesting... well explained for us understand.... Thank you
Great to hear. Thanks Amiga Dude!
I'm looking for a free converter tool which renders HAM images from any other modern format on a PC.
Is this possible to do the same process on WinUAE and Windows 7? My goal is to send Jpeg files (as an converted iffs) to adf image disc file.
Yes, absolutely. It works great with WinUAE
@@TheGuruMeditation currently I am finishing game written in AMOS 1.4 on Amiga 500 with 1MB RAM. Title of the game is SUPER PUZZLE, and it is computer jigsaw, where player need to create original picture from randomly set fragments. Currently in the game, are pictures that I created in Deluxe Paint 4 in 1999. These are silouethes of Disney cartoons: Pluto and Simba from The Lion King. I dont have any rights to use this graphics, so I decided to change this pictures to photos of my pupils: a Cocker Spaniel, Cat and Guinea Pigs. All I need to do is to transfer photos from JPEG format, into Amiga 500 Half-and-Modify (320x240px with 4096 colors) IFF files, and then ... transfer those IFF to one ADF file which will be open from WinUAE level and readable by Deluxe Paint and AMOS 1.4. I will be very gratefull if You will help me in this effort I will discover some difficulties. Greetings from Kalisz, Poland!
I'd love an episode about CDXL video ;-)
How does the HAM mode compare to the Atari 800 chipset where there were similar tricks for displaying all 256 colors? :)
I am not sure. I am not familiar with the Atari 800's graphic capabilities but it is something I should learn - especially for out upcoming Jay Miner tribute exhibit at VCF East!
@@TheGuruMeditation Look forward to the tribute! Jay deserves much respect!
@@TheGuruMeditation Definitely check out the 800 chipset, you can easily see where the Amiga came from :)
@@jrherita I can talk to Joe Decuir about it directly as he will be part of out Atari 40th/Jay Miner tribute exhibit at VCF East this year! twitter.com/TheGuruMeditate/status/1108715132492922881

Thanks! We did a follow up as well. I am editing that now so stay tuned! -- Bill
Another awesome videos guys!
Now my fingers are tickling and i want to repeat your technique on my real 1200. :)
I am also considering using Personal Paint and Deluxe Paint to compare the results with ADPro.
Nice Alex! Do it! The is nothing like using the real machine. I have WINUAE and FS-UAE and they are both great, but there is nothing like the real thing! A comparison would be cool. Although, I don't believe DPain can read JPGs and convert them to IFF, but I haven't tried that in decades. I used to convert with ADPro. All the best! -- Bill
By the way, Digital Creations' DCTV (which came with the fantastic DCTV Paint) used an even more clever method of storing 21 bits of video data into 4 or 6 bits. You could even render DCTV animations that played at 30 fps or more (since the Amiga just treated it like a normal display mode). Very very cool. Wish I still had mine!
JW3HH
Yep, I love DCTV. I used it all the time. It was my goto. However I never tried doing video with it. That will be a great project. I used DCTV for part of our Amiga exhibit at this year's VCF. You can see it in action here: th-cam.com/video/HEIesAtmKfM/w-d-xo.html Thanks for the great comments! -- Bill
Yeah, in the days before the internet I somehow came across an Anim-5 video (remember those?) that was to be played on a DCTV. I don't remember what it was (I think it was a clip from one of Pixar's early shorts like "Red's Dream"), but it looked AMAZING, especially for the time. Yeah, DCTV was an awesome piece of hardware and DCTV Paint was actually a very capable paint program as well.
JW3HH
p.s. Have you guys ever tried/reviewed the MiST FPGA Amiga/Atari ST system?
oh yeah, Anim-5. That brings back memories! wow. I have to get some video cooking on my DCTV. No, we haven't got our hands on a MiST FPGA yet, but it looks really awesome.
Great video guys! (Extra points for Kings Quest insert)

what version of adpro are you using there and is it avalible for free, my version is some old one with a huge gfx gui interface, not system gui interface like yours
Great question. The version with the GUI that you know of is the original. This is version 2.5 which is the last version. They re-designed the interface. Technically it isn't available, but it is out there if you know the right channels. If you send me an email I can point you there BillATthegurumeditationDOTorg

Actually PhotoShop did drop iff for a couple of iterations but then brought it back.
Cool. Didn't know that fun fact. Thanks Richard! -- Bill
You are welcome, I have been teaching people how to use PhotoShop for about 20 years now for an adult continuing education center connected to The University of Missouri St. Louis. I have been enjoying your youtube vids and missing my 5 Amigas that I once had.
Oh neat! Good for you. I love Photoshop. The more I learn about it, the more I realize I don't know. I do cinematography for a living, and occasionally shoot some stills as well so I have a basic feel for it, but it can do so much I feel like I have only scratched the surface. It is an incredible tool especially when put into the right hands! Thanks so much for watching our channel and the kind words. Really appreciate that and am glad you are enjoying it. We have some really exciting stuff on the horizon - especially when it comes to photography and video on the Amiga. We are just getting warmed up! All the best, Bill
The AMIGA was way ahead of its time, like 5-6 years ahead. Too bad they couldn't keep innovating.
whats appropriate is the building with H&M on it...HAM!
Ahhhhh ha ha ha! Good eye! I should go into DPaint and change the "&" to an "A"
here at raw.githubusercontent.com/nitrofurano/luascripts/master/scripts/gluas/amigaham.lua i have a gimp-gluas script that aims to get closer to a ham6 conversion result (i only used those “primary distortion” colours 16..63 - i still have no idea how to better quantize the best 16 indexed colours )
That's awesome Paulo, thanks!
really, really great talk :)
Thank you so much! Appreciate that!
would have been good to compare with HAM8 mode.

When I first saw the DigiView pictures I was already used to 24bit images so I thought they were garbage and I thought it was just a toy computer trying to punch above its weight. I am even more convinced of that now I know those HAM6 images are basically useless.
Also: Typical of Amiga fans a lot of this "Unlike on other computers" comes from people who clearly don't know how other computers work: The three letter file extension talk is garbage. The three letter file extension serves as nothing but an organising label for file managers. In most even remotely well written apps they use the header contents for validation testing, not the three letter extension.
"I had a Mimetics frame bufffer which allowed for /basically/ 24bit images to be displayed". Which Mimetics frame buffer? Is there more than one? The only Mimetics frame buffer I know of can only display 21bit colour. That's what you mean by "basically" 24bit, isn't it? What you mean by "which allowed for /basically/ 24bit images to be displayed" is "but it did not allow 24bit images to be displayed". Go on, Amiga fan base, start telling the truth for the first time in your lives.
"A 320x200 getting blown up to 1920x080 which this video is gong to be in is really going to give you a massive amount of artefacts". Yeah.... in other words, what it is going to do is reveal what HAM6 *really* looked like and you don't want other people to have the same disappointing experience I had so you're showing what could NOT be done on an Amiga for the first 7 years of its life, and by the time it could do what you're showing there were plenty of better graphics cards for the PC.
"I'm going to use a Mac...", because even the Amiga fan accepts they'd be a fool to try picture editing for the Amiga actually using the Amiga, this alleged graphics superpower.
"That's a hard image for HAM...". No it isn't. It's mostly smooth graduations of almost primary colours. It's approaching the easiest kind of picture for HAM to emulate. What you want for a real test is a very noisy reference image with lots of very different colours grouped as closely together as possible in the x direction. That's what HAM can't do: High density colour images.
The wikipedia description of HAM mode goes like this:
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
HAM6 encoding uses six bits per pixel: two bits for control and four bits for data. If the two control bits are both set to zero, the four remaining bits are used to index one of the 16 preset color registers, operating in the fashion of a normal indexed bitmap. The other three possible control bit patterns indicate that the color of the previous pixel (to the left) on the scanline should be used and the data bits should instead be used to modify the value of the red, green or blue component. Consequently, there are four possibilities:
Set: Use the 4 bits of data to index a color from the 16 color palette. Use that color for this pixel.
Modify Red: Hold the green and blue color components of the previous pixel. Use the 4 bits of data as the new red color component of this pixel.
Modify Green: Hold the red and blue color components of the previous pixel. Use the 4 bits of data as the new green color component of this pixel.
Modify Blue: Hold the red and green color components of the previous pixel. Use the 4 bits of data as the new blue color component of this pixel.
&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&
There was also a HAM8 mode on AGA Amigas and a third party HAM-E by Blackbelt Systems that was similar to HAM8, but at low resolution (AGA HAM8 can use any horizontal resolution, including 1280).
Another variation was "sliced HAM" (you can't make this stuff up...) or SHAM, where the palette could be changed on every vertical line. This added more freedom to where you could put colors, but was more system hungry. I remember being blown away by pictures displayed in this mode. HAM8 made this mode obsolete.
The "fringing" you speak of can be greatly reduced or even eliminated with very careful palette selection and pixel data. (There were programs back then that could analyze your HAM image and reorganize it for this purpose).

Cool! I'll check it out! I think it's so great that retrocomputing has become so popular in the last few years: New games, new hardware, shows in all parts of the world devoted to those old computers and so on (And not just the Amiga, either. Commodore 64, Sinclair Spectrum, Atari STs and so on have lots of support from their devoted fans. Some of the FPGA hardware out there is really fascinating (and not that expensive, either!), including a 200+ mhz 68060 accelerator for the A600 (I think it's called Vampire).
It's very exciting! Some group is even "rebooting" the C64 with higher quality video (HDMI and/or S-Video), sound and so on. They even licensed the official Commodore ROMs, etc. Nice!

Why extend the canvas by one pixel rather than just rescale the image to the 724? Did you also save as lossless JPEG because otherwise you are added additional artefacts into the image which the HAM mode has to render.
Hey James! Thanks for watching and the comment. I extended the canvas because if I made the width of the image 724 then the height would be 483 which would exceeded the maximum resolution of 482. Again, one line of resolution is probably imperceptible, but with an image of a different aspect ratio I would want to keep the 482 to maximize my resolution because I still have a lot more resolution in the width to play with. For example, if the image was 16:9 aspect ratio and I set the width to 724 then my height would be 407 and I wouldn't have the max resolution available to me. Instead I would set the height to 482 (the max) and my width would be 857 which fits in Super-High Res Laced Extreme Size 1448x482. When I made the JPG I set it to the lowest compression of 12. Is there such a thing as an uncompressed JPG? I never heard of that. I make uncompressed TIFF and PNG files all the time from my Camera RAW files, but I never heard of an uncompressed JPG. Thanks again for watching and commenting. I hope I was able to explain the method of my madness! Best, -- Bill
en.wikipedia.org/wiki/Lossless_JPEG
I would just rescale it to 482x724, for one pixel the change in aspect ratio would not be noticeable. Yes other lossless formats such PNG or TIFF would be more a better choice.
Neat. Thanks for the info about Lossless. I doubt ADPro can accept an image with that compression, but worth a try. It also doesn't have a loader for TIFF or PNG so I am not sure if it can bring those in. I'll have to give it a try. Although one could argue that regular JPG at 12 (Max) compression is pretty darn good.
Actually you want minimum compression (larger file) to be as near lossless as possible and therefore less JPEG artefacts ;-)
you mean an extra 482 pixels ;p
Hmmm ham sandwich 😋
he he, working in HAM mode makes me hungry! :-) -- Bill

Is that Debbie Gibson? Or did a lot of girls just look like that in 85?
Ha ha! No, that isn't her but I see the resemblance. That was the "look" back then.
Hi Guys. Its hard for me to write this because you are doing the great job, but i had to say it because your inaccuracy could mess in people head. Original Amiga chipset OCS, could display HAM mode only in Low resolution 320 (352 overscan) while the vertical could be 512 in PAL(or 576 overscan) or 400 in NTSC. You have used HAM6 mode on AGA so while you could display 640x480 HAM6 image in reality NOBODY would be interested in using that mode if for 2 bitplanes more you could actually have so much more . This makes the whole video purelly artificial and could convince newbie that amiga actually could do something which in reality it cant. Conversion to HAM6 mode is actually very difficult proces, because first you need to convert resolution to 320x480 then convert RGB24 to RGB12 then apply HAM compression. Each of those steps makes a difference and if you would do it wrongly the final effect will not be as good as it could be. It is also worth to mension that in low resolution mode the noise caused by dithering is much more visible making the whole process even more difficult and FS is not a best option here. Me and my friend are researching this topic in order to create the best ham converter (and recently also Dynamic Hires) and i can tell you it is very difficult. We also started to research Dynamic Hires which in fact allows you to display 640x480 picture on standard OCS machine and i posted some pictures here .www.imagebam.com/image/e4e1b9516025848 In Dynamic Hires picture contains 504 colours (843 in lowres HAM6) but only 16 in each line, while Lublin has 263 (725 in lowres HAM6) and also only 16 in each line. However you can see that Dynamic Hires blows away HAM6 picture thanx to higher resolution.
Hi Trachu. Thanks for the comment and the kind words. Yes I am aware that OCS does HAM in up to 360x576. In retrospect I probably should have stuck to those resolutions, but if you watch the video at 5:58 I explain that I am cheating and using higher resolutions because of the 1920x1080 upscale and conversion to mp4. I did have Dynamic HiRes in mind when doing this because I used to use that mode with DigiView all the time. I will never forget NewTek Demo Reel 3 with this announcement and image: th-cam.com/video/DybXc-WEf6Y/w-d-xo.htmlm49s My thinking was to use the higher resolution available on the A1200 but keep the 4,096 colors because I knew the image would be up-scaled to 1920x1080 for TH-cam so I wanted to minimize the amount of scaling. I briefly upscaled low-res OCS images to higher resolutions at VCF East and the quality looked poor on modern equipment and I felt that it wasn't a good representation of what you see with your eyes on the CRT monitor even in the OCS resolutions on a real Amiga. I certainly didn't mean to mislead anyone. Perhaps it wasn't the right decision, but I thought it was the best option at the time. It is still 4,096 colors which was my main goal. I will have to go back and experiment with the lower resolutions and see how they look when upscaled to 1920x1080 with mp4 codec. Good luck with your software. It sounds great and thanks for experimenting with the images. That is very cool. Please keep me posted with your progress. My one suggestion is that your software must maintain the original aspect ratio of the image regardless of Amiga screen resolutions. Otherwise it world force the photographer to use additional software and mental calculations to correct the aspect ratio. Obviously distorted images like the 2 you presented in that gallery are not acceptable even though that was a technical demonstration. Thanks again for taking the time to experiment with the images and providing some insight. -- Bill
352x576 not 360 - Amiga splits horizontal display into 16px chunks, so while you can set any resolution inbetween it will allocate DMA needed to feed nearest mod16 resolution. As for your conversion process, my point is that RGB24to12 conversion done in Lowres is much more difficult because applying nice looking dithering to Lowres is much harder than in Highres. Good portion of your video is praising dithering as the tool to make the banding go away. It is not as easy as you have described it. Basically what you have done is purelly theorethic. In AGA we have HAM8 which when done correctly can display pictures indistingishibles from originals. In terms of aspect ratio - I have included original files (just like you did) so anyone can take them and try to use other display programms to receive ham picture. Turning on interlace make the picture thinner, but it would display correctly on Amiga, that is why HAM6 output is doubled horizontally to mimic how it would look on real Amiga. If you want to see more Dynamic Hires pictures heres another link www.imagebam.com/image/26443f511709489
Yeah, in retrospect I should have just done it in Low Res, but I was concerned about the upscale to 1920x1080. I felt like a low res HAM mage upscaled to higher resolutions on a modern computer look worse than the same low resolution image on a CRT (I am talking about what is perceived by your eye), but I will experiment more with that. I should have just used 320x200 which is what I mostly did back then except for dynamic hi-res. So much for my modern twist, LOL. You should offer the correct max resolution to Wikipedia because it says 360x576 is max for HAM6, but maybe that is ECS?
Again, I totally feel you with the 24 to 12 bit conversion and dithering in low res, but I was trying to avoid the 5.4x scale to 1080 and all the side effects that come with that and minimize it to 2.2x upscale. I probably should have made low res images for the folder and used the workflow in the video to present the image on TH-cam. But either way converting to 1920x1080 mp4 is a bastardization of the original image anyway. But now you have me wrestling with my decision, lol! Let me know when you have your software up and running. I would love to play with it.
Hi Trachu! Is this your software? mrsebe.bplaced.net/blog/wordpress/?page_id=374 Can't wait to try this. -- Bill
