This series has been such a lovable introduction to photogrammetry, as a student studying 3D; thank you very much. You've made it far less daunting tackling such a seemingly sophisticated process!
A Seriously Good video. Very professional. Well done and thank you. I did like the huge head appearing over the car at the Florida Mountains scene. Even with reflections!!!!
Can't wait! Still can't un-see the blurry junk. I've got a pretty good Cannon dslr. You mention good lens quality. What kind of lens would you suggest for photogrammetry?
+Jason Baldwin Generally speaking, I think sharpness is the main factor you want to look for. Unfortunately, it's not always easy to find out how sharp a lens will be when browsing. But you will usually find that the more you pay, the better the glass will be. But you can still find good lenses for pretty cheap. The 50mm f/1.8 that I have is a very cheap lens, but it gives decent sharpness (when shot at tighter apertures) and the color rendition even looks better to me. If you find a lens that interests you, I would check to see if Ken Rockwell or someone else has made a review on it, and if you're still hesitant, you could always rent the lens first to see how it performs in practice.
Thanks for your videos and creative approach. It keeps me from falling asleep effect, which usually takes places with this kind of videos, gives kind of energy to better absorb the information you provide. Keep it evolving. Harmony in Cooperation.
I swear you really look like that kid from Jurassic Park 1. You know, the one from the intro who's like "that doesn't sound scary" and then Grant proceeds to draw the raptor claw across his belly. Anyway, fantastic series, I'm learning so much!
Very Inspiring tutorial mate!! Love that you included th 12 Apostles in your scan examples. They are only a 2 hour drive from my place in Victoria,Australia =)
Thanks, Mark! I hope to have the next installment out within 3 months, the current video I'm working on is eating up a lot of my time. But I hope it will be worth the wait!
+evilkoolade Thanks! I'm currently working on Part 4, I hope to have it uploaded in January. There's a lot of new content being generated for it, and I'm also building a new computer to showcase better scans.
Thank you so much!!! Ive been getting good results with your tips. Can you please make a video on the after effects part of exporting your images. I got the basic workflow of the green screen process down, but am having the hardest time figuring out how to export properly to get a 1:1 input to output of images.
+Thomas O'Hare Hi, Thomas! Do you mean you end up with a different number of masks compared to the number of original images? If that's the case, you may want to enable "force alphabetical order" in the image sequence import dialogue. That way, if you deleted or just didn't use some of the images you shot, AE will ignore the gaps. If it's another problem you're having, let me know. And thanks for the kind words!
Hi James. I was waiting for the camera to drop down again after the first 10 sec;) These 3 episodes are really great! One question... So I've tried creating a photoscan from a tree. But when walking around a tree the light is different from the front and back depending where the light is coming from. So the scan has baked in lighting. Any cool methods to fix this without haven to manually change the exposure and stuff per foto? (The team from Unity Kite demo used sort of a anti shadow to get rid of the baked in shadows....) Cheers, Marcus
Hi, Marcus! I know what you mean, trees and other round objects present this problem of shadow. Here are a couple links that might help you: dmg3d.blogspot.com/2015/09/removing-ambient-occlusion-from-photo.html morganmcd.com/?p=6776
+Pierre Benjamin I'm planning to have the Head and Body scanning guide done before the spring. First, I'm finishing up the man-made environment scanning video, which will cover both interiors and exteriors. Until then, I recommend Jeffrey Ian Wilson's guide: vimeo.com/98638688 It's long but well worth the watch!
Thanks, I never knew what the name of it was when I was editing the video! That's really cool that you've actually been there, it looks so majestic (especially compared to the endless flat land here in Florida).
Your welcome! Great video by the way, I've just been getting into photogrammetry these past few days, only on small objects currently, but am looking to eventually recreate an outdoor environment or two for Steam VR, so this helped me out quite a lot, thanks! I hiked up Ben Nevis with a friend the day before we visited Skye, I did actually take a photo of this exact bit of land from close to where this was taken, but I had the wrong settings on the camera and it came out too blurry when I blew it up on the PC :( these are more large hills than mountains, but the natural landscape is quite breathtaking to look at, and the Isle of Skye is really quite a tranquil place in general... apart from the hordes of midgies!
Ah, I hate it when I screw up a picture and don't realize it until I see it on the computer! I'm sure you'll be able to work your way up to large environments before too long. I think it's best to progress as you are- starting with small, easy to scan objects, and working your way up to gradually bigger and bigger subjects. By the way, I had to look up what midgies were- I thought "maybe seagulls?". Nope! Haha
ClassyDogFilms I'm sure I will! I've been interested in photogrammetry for a personal project I'm currently working on in Unreal Engine. Your videos have been an invaluable resource, your great sense of humour makes them light and easy to watch and come back to. can't thank you enough!
Thank you, that's very encouraging to hear! I do my best to keep the videos informative while still being fun to watch. The script for the current video has gone through 11 iterations already, it was a real challenge!
I've never used a camera with depth sensors yet, and I'm not sure if any of the photogrammetry software supports any of them yet, but I'm sure in the future they will become more supported!
Thanks for these great videos. Question: Do I need to buy the Pro version to do environment scanning or will the Standard version work. Big price difference! Pros / Cons
Thanks! The Standard/Basic version of PhotoScan should work for just about any type of project, environment scanning included. The pro version comes with advanced stuff that I honestly don't even understand half the time, but it's intended for top level scanners who need the very specific tools to refine their results. But I think most of us are unlikely to ever need those extra tools, so the basic version should be enough!
Fantastic. Thank you for your fun and informative channel. Quick question. Do you know if it is possible to stitch together drone photographs taken from different elevations? IE would it be possible to combine low flying images taken underneath tree canopy and combine them with images taken at a higher Ie 250 ft elevation ? Thanks again for sharing your expertise.
Hello, Gregory! Apologies for the delayed reply. I believe you shouldn't have a problem with changing the elevation like that- the only thing I would recommend avoiding is any change in focal length while shooting, since I believe the newer versions of Metashape (if that's what you are using) don't like aligning multiple focal lengths into the same scene. Having said that, I would recommend shooting a small test scan just to get an idea of what kind of results you might expect before shooting a larger area. I hope that helps!
subscribed !!! want to ask Do i need a camera with GPS funtions ? to align photo ? i am buliding UAV for mapping now i only lacking of camera.... any reply in this will highly appricated... i am looking again how to measure distanct like scales tools .... normally i export to tiff and mesure using QGIF ... any solutions that i can just do everything in a agisoft
+Uni Productions Thanks! I know that GPS data is not necessary for large area scanning, but it can help. I have never done any of it myself, but I know many people have. I recommend checking out the 3D Scanning Users Group on Facebook: facebook.com/groups/1439036619645915/ There are some very talented scanners on there who should have more specific answers for you relating to that field. I know there are dedicated tools in PhotoScan for georeferencing and stuff like that.
+Gary Whaley Thanks, Gary! I hope to have part 4 out within the next 2-3 months (I'm building a new computer to be able to generate higher quality scans, so that's adding a little time to the process). I have a lot of tips I'll be covering in it. Thanks for watching!
Thanks, Tzur! If I'm shooting handheld I'll generally refocus each shot with AF. If I'm shooting on a tripod, I usually set focus manually and refocus when enough movement has occurred. It's tedious, but sometimes AF is inaccurate.
Very nice and didactic&fun style of the video! Thank you for sharing! I am actually having troubles scanning a big tree, it seems the program don't recognize part of the pictures as there are many big roots on it.I saw some people use simple stickers to help the program identify better the scanning.What do you suggest? Thank you in advance :)
Hi, Jose! Certainly, you can stick markers or other things into a scene to help the software better identify areas, but I would be surprised if this is necessary for any part of a tree. Would it be possible for you to share an example image from the shoot? It may be that the tree roots are underexposed a little too much, since darker areas tend to get ignored.
Hi. This is great stuff! Are any of these environments available for downloaded so I can view them within my VR headset? I'm particularly interested in a forest or woodland environments, something with vegetation.Thanks!
Hi, David! Unfortunately, I think I deleted all of them years ago to regain harddrive space (I really only shot them for the tutorial), but I will try to do some more in the coming year and make some of them available for free. I do have some free tree textures on my Gumroad page if you ever need those. And I know The Terrain Domain also has some freebies that you might find interesting. I hope that helps!
Do you think I could scan my body into a playermodel? I could stand in the t-pose and rig it after. I'm using the software so I can make a videogame. Houses too, would it be hard to do houses?
You could definitely do both bodies and houses! I'm working on the next PhotoScan guide right now, which will include how to scan buildings. For scanning your body in a T-pose, it will help if you have something solid to hold onto, like poles or something, to keep your hands from moving too much.
Such a good video. I've just today started looking into this. Considering it's reasonably easy to obtain tons of scans, you'd think there would be a few resources to download free scanned objects to try out/take a look at. I really can't find any.
+cr0uchingtiger You're right, there aren't! A fellow scanner, Daniel Morrison, has a website he uploads a lot of scans to. Here is the address: www.remnantstudios.com/freebies
How does this work if the environment changes? Like let's say I take a bunch of pictures of a model railroad while the trains are running? Will the software just error out, or blur it together, or come up with a result that makes sense?
It's hard to say what will happen, as I've never tried it myself. As long as most of the area in the images is static and non-moving, the result shouldn't be too bad. I recommend trying a small test first if you can. For greater control of the scan, you could mask out the train and any other moving parts. Or if you can shoot with a tripod, you could take multiple exposures from each position, and just combine them to remove the train. But only attempt that method if you can shoot with a tripod and preferably a shutter release, as any camera movement will ruin it. Masking may work just fine, if it's even necessary.
Sooo I dont know if you're around anymore, but would be awesome if you had a answer. What is a optimal distance towards objects? Is there something you should watch out for? what is a good CHEAP equipment for poor VFX Indies to go with when they're trying to do air shots? I heard you require a closing time of 1/60 or a really high stability to get good pictures. This might be difficult to acquire when a drone gets hit by wind. Furthermore occlusion and so on gets into this.. so do you have some tips recommendations or tuts?
Hi! You know, I've still never used a drone, so I can't really give much info about them. It might be a case where you have to spend a bit of money to get one that can get the job done in less than ideal conditions. But I really can't say without having any experience using them. However, I do know a good deal of people on the "3D Scanning Users Group" on Facebook who use drones in their work, with great results. I would recommend asking there, as they're sure to have some helpful suggestions!
darty367 Those are both excellent suggestions! I will add all the links into the description tomorrow, and figure out how to upload subtitles to this video very soon!
i just started using the software and found this software tutorial really helpful. Are the images required to be geo-tagged too ? How can I measure / add scale to the pictures and the final model that is prepared?
Thanks! No, your images don't need geo tagging, but I believe you can use that in the Pro version for more accuracy on big areas. I've never tried measuring or adjusting scale, but there is a really great FB group that can answer that. Just search for "3D Scanning Users Group". Hope that helps!
Great Video and fun, too! Thanks a bunch for making it. I have a question concerning post processing scans. I came to use realityCapture,which is a great alternative for photoscan. It is pretty fast even for large amounts of images and I've heard it beats photoscan so you might wanna give it a try some time. Anyway, it produces pretty large meshes. It does have a simplification tool, but not a very sophisticated one. I am looking for some proper software to remove artifacts, smooth parts of the mesh, remove complexity where it isn't needed and the like. What do you use for post processing and what can you recommend? Currently, I work with Blender but I feel there must be better options. Again, thanks for the fantastic video. Cheers Ole
Hi, Ole! You're right, RealityCapture is a great program. I hope to try it in the near future! I don't have a lot of experience outside of Blender, but I know many scanners like to use zbrush. It can handle those big meshes easily compared to Blender. It is a bit of money to purchase, but if it can fit your budget, I'm sure it could pay for itself quickly in time saved. I intend to buy a license myself next year. Thank you for the kind words!
ClassyDogFilms thanks for the reply! I'll have a look at zbrush. Seems to be a good hint. Blender can reach its limits quickly and nothing is worse than a crash after an hour of tedious work on a huge mesh. Zbrush would pay itself via all the equipment I don't smash in frustration :) Hope to see more of your tutorials in the future. Best, Ole
ClassyDogFilms By the way, what do you make of googles project tango and the Lenovo phone that works with it. Those seem to do a decent job of photogrammetry in real time on a mobile device. Do you think that can compete with a DSLR photogrammetry result? Probably no way to tell yet, but I am thrilled. Should be available this year
I know what you mean, just importing a huge mesh can takes ages in Blender. And I have heard about Project Tango, but I haven't really looked into it. I do think that DSLRs will still give the best results for a while, due to their resolution (especially when using the huge MP cameras), but I'm sure the real time stuff will catch up fast in the coming years!
Hey, Ive been making short films for a little while now but its been with a small handheld camera corder. While it got the job, I want to get a DSLR to be able to get better quality, change lenses, focus better, ext. I would like your opinion on a DSLR that costs under $400 that can get good video. BTW I'm not opposed to getting a used camera since this is my first DSLR. Thanks
Jon Parizo Hi, Jon! I would recommend looking for a used (but well taken care of) Canon t2i or t3i. If you want a flip-out screen, the t3i is the better option- otherwise the cameras are about the same. I bought my t2i new back in 2010, and it's still the only camera I use for both photos and video. Some people may tell you it's not good enough, or if you want to scan that you should get this or that- but a cheap Rebel dslr gets you the most bang for your buck, and is an excellent camera to start with. You can find some good deals on ebay. If you have anymore questions, just let me know!
I'm expecting to have it out in January (currently busy with a couple other videos). But the script is complete, just waiting to have time to shoot it!
Hi I've not managed to get the quality u r getting on aerial drone scans ? I have apps 200 photos for a plot of land shot from magic pro . It's ok ish but just not like any I am seeing online ? Any ideas thankyou
Hi, Trevor! I've still never used a drone to shoot scans myself, but I'll offer some guesses as to what might improve your drone scans. It might be the time of day: Are you getting a lot of light for a good, sharp exposure on the camera? It could also be your subject matter: stuff like castles and mountains are probably a lot easier to get good looking scans than a plot of land will be; not just because the former is more interesting, but because their features are much larger, and therefore easier to capture from a distance. If you're scanning dirt, you might have to get closer and shoot many more photos. Those are just some ideas, feel free to upload a sample picture though if you still have trouble!
hey. got question for you. is it good to produce 3d images using images got from video, like action camera? if so, can you suggest methods/ideas to get great 3d images from it. thank you.
Yes, you actually can get good models from video. I'll talk more about this in a future video, but generally you'll probably want to shoot a little closer than you do for still images, because the compression in the video will erode details a little bit. The higher the bit-rate you record your video at, the better quality of the scan will likely be. For example, the Panasonic GH-series of cameras will give a decent result due to allowing you to shoot at higher bit-rates than most similar cameras. I would suggest doing a test run and seeing what kind of results you get with the camera you have- that will tell you if you need to shoot closer (or slower).
maayaa77 Thanks! You might say I "wood" be hard pressed to find a better compliment. Get it? Like the wood of a tree that was scanned? Ah, yours was better... Thanks for watching!
great video, very informative & funny! I have yet to experiment / use agisoft photoscan, but I am looking forward to it. What potential issue and success do you see with taking photos with a 360 degree camera (ricoh theta)? There may be worst photo distortion than a fish eyed gopro, but maybe theres an easy fix that'd result in better & faster environmental photo coverage. Thoughts/ideas?
+Dogma 360 Media Thanks! It's tricky to say, as I've never tried it myself, but I do believe it's possible to get some kind of result from 360 degree images with PhotoScan. I can't say how good the quality would be- as you know, the wider the field of view of your images, the fewer images you have to take, but the lower resolution the details become. Having said that, you could always combine 360 degree shots with normal photos to find a balance that works for you. The other great thing about cameras like the Theta is that you can capture IBLs when you're scanning to aid in de-lighting your textures later on! I hope to cover that in the next tutorial.
Mason Menzies I myself still use my Canon t2i, which I bought new back in 2010. It shoots RAW, and can be found on Ebay for around $250 USD I believe. There are newer Rebels available as well, such as the t3i with a swivel LCD screen (can be very helpful), but other than that they're pretty much all the same image quality. If you're on a budget, I'd look for an older Rebel model rather than a newer one.
Mason Menzies And when I say a "newer" Rebel models, I mean like the t5i or t6i. I'm sure they're slightly better cameras, but it just wouldn't be worth the extra cost of buying them, especially because they're probably way over your budget.
I've been using my iPhone 6s Plus to scan object and I've been getting some ok scans but when apple allowed raw image capture on iOS 10 using adobe lightroom on my phone I was able to capture sharp clear images. I've ran into a bit of a problem tho. Agisoft photoscan recognizes the images but it doesn't process the data correctly for some reason. Tiff don't work so I was forced to export as a jpg. But I have to say the image quality was still higher than the jpg before. Images scans where 3 times better.
That's really encouraging to hear! I've never tried it myself, but I think phone cameras have finally caught up to be able to generate decent quality scans. I bet if you made a short tutorial about it, a lot of people would be interested to see it!
+Potatowarrior 13 Thanks! I hope to have the next PhotoScan video up in a couple of months, just saving up to build a new workstation first. I have some special things I want to show in it.
I'm interested in applying this using a drone with/or a camera. Do you have software you recommend the most? Is there anything that makes masking super easy for when you have to do dozens or hundreds of images? Final question- do you do anything with copyrighting the things you develop? Some of the demos you showed were incredible- I imagine there's people who would love to make use of them either for film or printing- do you license some of them or no?
You can definitely get good results with a drone. Generally, I would recommend either Agisoft PhotoScan or Reality Capture. There are other programs out there, but those two are very well known and give excellent results. For masking, I know you can create Photoshop actions to help speed up the generation of masks. How you decide to create the action depends largely on images themselves, but you can use things like luminosity and color to create selections. I think you can even make selections based on sharpness. And I've never licensed or copyrighted any of the scans seen in the videos, but I also haven't saved any of them, either. They got deleted years ago in order to free up space on my old computer. But in the next video, I'll be making the scans shown available on Sketchup for free download!
Hi ! When you take your several photos of the subject, is it possible to get closer to the subject without altering the lens configuration for more details, or we have to stay at the same distance all the way around the subject ?
You know, I'm not certain, but it may depend on which photogrammetry software you're using. I think some don't care if you change the lens (such as the focal length) while shooting, and other do. But I don't worry about changing the focus, I do that all the time and never have problems with it. I don't believe maintaining the same distance from the subject really matters, as far as getting a good mesh result.
This guy's weird ass sense of humor is right up my alley.
Thank you!
Indeed, this is a tutorial on how to make a tutorial.
Dude, I love you - this video is everything.
This series has been such a lovable introduction to photogrammetry, as a student studying 3D; thank you very much. You've made it far less daunting tackling such a seemingly sophisticated process!
I'm delighted to hear that! I'm glad the videos have been helpful to you!
I really enjoyed that video. "Find the box, scan it and think outside it", or "occlusion hell" are my absolute all time favorites hahaha
Haha, thank you! I'm looking forward to making more scanning videos in the near future.
@@ClassyDogFilms Please do so. It´s always very entertaining =)
I am a complete beginner to photogrammetry and I am so glad I found your videos. Looking forward for the next one.
I'm very happy to hear that! I hope to have the next one out before the year is over.
A Seriously Good video. Very professional. Well done and thank you.
I did like the huge head appearing over the car at the Florida Mountains scene. Even with reflections!!!!
Haha, thank you!
I just discovered your videos - they are BRILLIANT, thank you. Informative and witty.
Thank you! I'm delighted you enjoy them!
This was my first look at photscanning and it could not had been better! I really enjoyed this episode and all the useful tipps and links!
+Univers VFX Thanks! I'm really happy you enjoyed it and found it useful! I should have a new PhotoScan guide finished in a couple months.
+ClassyDogFilms I'll be there!
Man you've got instant friend persona, hilarious and awesome vids! Thank you!
Thanks very much! I hope to release more videos soon!
This is, hands down, the best tutorial out there. Fantastic work!
+Jason Baldwin Thanks, Jason! That means a lot to me. More PhotoScan guides coming soon!
Can't wait! Still can't un-see the blurry junk.
I've got a pretty good Cannon dslr. You mention good lens quality. What kind of lens would you suggest for photogrammetry?
+Jason Baldwin Generally speaking, I think sharpness is the main factor you want to look for. Unfortunately, it's not always easy to find out how sharp a lens will be when browsing. But you will usually find that the more you pay, the better the glass will be. But you can still find good lenses for pretty cheap. The 50mm f/1.8 that I have is a very cheap lens, but it gives decent sharpness (when shot at tighter apertures) and the color rendition even looks better to me.
If you find a lens that interests you, I would check to see if Ken Rockwell or someone else has made a review on it, and if you're still hesitant, you could always rent the lens first to see how it performs in practice.
Thanks so much for the advice! That's super helpful.
Nice. You remind me of a young Ron Swanson from Parks and Rec
Thanks! I haven't watched tv in about 7 years, but I know exactly who you're talking about.
Thanks for your videos and creative approach. It keeps me from falling asleep effect, which usually takes places with this kind of videos, gives kind of energy to better absorb the information you provide. Keep it evolving.
Harmony in Cooperation.
Thanks! I hate when how-to videos get long and boring, so I try my best to keep my videos fun to watch!
Thanks for the video and good tip on the bonsai. I'll try it with it.
I'm glad you enjoyed it! If you try it, post your results, I'd love to see what you come up with!
Amazing...I like the way you explain things.
Thank you, I'm glad you enjoyed it!
Awesome series, great job.
Thank you very much! I hope to have the next one out soon, it will have a lot in it!
I swear you really look like that kid from Jurassic Park 1. You know, the one from the intro who's like "that doesn't sound scary" and then Grant proceeds to draw the raptor claw across his belly. Anyway, fantastic series, I'm learning so much!
Haha, thank you! I have a lot planned for the next PhotoScan video, I hope you'll enjoy it.
You got a thumbs up for your 'Great Florida Mountains' alone.
But the rest of the video was very informative, thanks very much.
Thank you, I''m delighted you enjoyed it! It was a lot of setup for that one gag, especially.
Love that slide in entrance.
Haha, thank you!
Excellent overview and a lot a fun to watch!
+RimGeurts Thanks! I hope to have the next installment up very soon (working on it right now)!
Really helpful. Looking forward to part 2.
Taylor Moore Thanks, Taylor! I've got a lot planned for the next video!
Great video! We are just starting to play around with PhotoScan for modelling rock art in South Africa and this has been such a help :)
That's wonderful to hear, I'm glad my video was helpful to you!
Can not wait for part 4 and 5.. :)
Love your sense of humour very similar to mine.. :)
Thank you! I hope the future installments will be just as fun, if not better!
Awesome Tutorial! wicked sense of humour! Find a Box, Scan it. Then think outside it!
Glad you enjoyed it! I can't wait to get the next guide done for you all!
Very Inspiring tutorial mate!! Love that you included th 12 Apostles in your scan examples. They are only a 2 hour drive from my place in Victoria,Australia =)
David Fromholtz Wow, that's cool! I'd like to travel to Australia one day; I'll have to remember to pay a visit to them!
Glad you enjoyed the video!
That definitely did not suck. Thanks so much.
I'm glad you enjoyed it, Tabb! I'm wrapping up work on the next one right now!
Excellent! Thanks for the video!
Thank you, I'm glad you enjoyed it!
Thank you for advice Zach. By the way, when hangover 4 is coming out ?
Thank you! Summer 2025!
That was the best overview i have ever seen
+Dominik Kaiser Thanks so much, Dominik! Glad you enjoyed it!
This is awesome! Thanks ClassyDogFilms!
Thanks, Scott! It's good to see you again!
Well made and informative tutorial. Thank you
thinkingbigthoughts I'm happy to hear you enjoyed it! Thanks for watching!
I liked the editing/style of this video
RottenCrack Thanks! I try to fit a few jokes in there to keep things entertaining.
This thing is so insane thank you for the information!!!!!
Thank you! I'm glad you liked it! I'm working on the next one right now.
I have to ask are you the hipster son of Ron Swanson from Parks and Rec ?
Yes, but Dad made me shave it.
'...the wise photoscanmaster can make a small rock look a boulder asteroid like...'
thanks merry Classy Dog !
Great video. Very detailed information.
Fredrow Gaming Thanks, Fred! I wanted to make sure I didn't forget to include any useful info. It took almost two months to make!
great tutorial, lovely weird and straight to the point. Subscribed :)
Thank you, Dimitris! Sorry for the late reply!
that was informative and fun :-D good stuff subscribed
Thanks, Joseph! I'm happy you enjoyed the video! The next one should be out next month.
Not watched yet but that slide onto camera at the start was worth a like on its own :D
Thanks, I forgot about that! It took like 5 takes to get right.
Ok, watched it now (along with 1 & 2). Really great stuff! Esp. on setting up the camera. I'm all subbed up for part 4 of this :)
Wow, thank you! The next PhotoScan guide will be uploaded after the next video goes up. It will be the biggest guide yet by far!
Nice stuff, James!
Now I feel ready to look like a mad men in public shooting people sidewalks. (y)
Thanks, Guilherme! I like to wear a ski mask when I shoot sidewalks (cuts down on reflections).
Hahahah, I heard a sponge bob costume could help with some warm bounce lights, well. I gotta try.
Good idea! Maybe I should include a section on scanning fashion in the next guide.
Do you have any ideas about how to compare the success of two different scans made from the same image set apart from simply visually accessing them?
Haha thanks brother. Informative and funny.
Thanks very much! I can't wait to get the next part done for you all!
Nice work, thanks for sharing
Do you recommend buying the next gen Barbie PC, or going for the current Power Rangers PC for high end VFX work?
I'd recommend the Barbie PC if it's within your budget, as I hear it's next-gen architecture is FABULOUS.
Get A Mono Pod!! Love it!
Just found this and love your style! :-) Keen to know if you're still doing this kinda stuff.
Thank you, Craig! I am still scanning a lot of stuff, and hope to have another video out on it before long!
More of a fan of the Pix4D software as we use it primarily for survey photogrammetrics, but totally enjoyed the video mate. Two thumbs way up!
Thanks for the kind words, Brian! Glad you enjoyed it!
awesome video thanks!
+Jean-Marc Fueri I'm glad you enjoyed it!
Really nice series, but where's the next part?!?!? I'm on the edge of my seat...
Thanks, Mark! I hope to have the next installment out within 3 months, the current video I'm working on is eating up a lot of my time. But I hope it will be worth the wait!
This is great when is the next part of it happening?
+evilkoolade Thanks! I'm currently working on Part 4, I hope to have it uploaded in January. There's a lot of new content being generated for it, and I'm also building a new computer to showcase better scans.
Thank you so much!!! Ive been getting good results with your tips. Can you please make a video on the after effects part of exporting your images. I got the basic workflow of the green screen process down, but am having the hardest time figuring out how to export properly to get a 1:1 input to output of images.
+Thomas O'Hare Hi, Thomas! Do you mean you end up with a different number of masks compared to the number of original images? If that's the case, you may want to enable "force alphabetical order" in the image sequence import dialogue. That way, if you deleted or just didn't use some of the images you shot, AE will ignore the gaps.
If it's another problem you're having, let me know. And thanks for the kind words!
Hi James. I was waiting for the camera to drop down again after the first 10 sec;)
These 3 episodes are really great!
One question... So I've tried creating a photoscan from a tree. But when walking around a tree the light is different from the front and back depending where the light is coming from. So the scan has baked in lighting. Any cool methods to fix this without haven to manually change the exposure and stuff per foto?
(The team from Unity Kite demo used sort of a anti shadow to get rid of the baked in shadows....)
Cheers,
Marcus
Hi, Marcus! I know what you mean, trees and other round objects present this problem of shadow. Here are a couple links that might help you: dmg3d.blogspot.com/2015/09/removing-ambient-occlusion-from-photo.html

+ClassyDogFilms Excellent James. The Unreal delighting process revealed:) going to give it a try.
Keep it classy! :)
Hello! when is the announced head and bodies tutorial due to be released please? would love to see it thank you!
+Pierre Benjamin I'm planning to have the Head and Body scanning guide done before the spring. First, I'm finishing up the man-made environment scanning video, which will cover both interiors and exteriors. Until then, I recommend Jeffrey Ian Wilson's guide: vimeo.com/98638688
It's long but well worth the watch!
thank you very much
informative and funny! great job thanks.
Thank you, I'm glad you enjoyed it!
Hahaha that was great. I like your face. and humour. You win todays internet
Thank you! I'll share my winnings with you.
HA! Loved the ending
+Pretty Neat VR Thanks, Billy!
2:22 Isle of Skye in Scotland! Weird how I just recognised that having only been to that spot once!
Thanks, I never knew what the name of it was when I was editing the video! That's really cool that you've actually been there, it looks so majestic (especially compared to the endless flat land here in Florida).
Your welcome! Great video by the way, I've just been getting into photogrammetry these past few days, only on small objects currently, but am looking to eventually recreate an outdoor environment or two for Steam VR, so this helped me out quite a lot, thanks!
I hiked up Ben Nevis with a friend the day before we visited Skye, I did actually take a photo of this exact bit of land from close to where this was taken, but I had the wrong settings on the camera and it came out too blurry when I blew it up on the PC :( these are more large hills than mountains, but the natural landscape is quite breathtaking to look at, and the Isle of Skye is really quite a tranquil place in general... apart from the hordes of midgies!
Ah, I hate it when I screw up a picture and don't realize it until I see it on the computer!
I'm sure you'll be able to work your way up to large environments before too long. I think it's best to progress as you are- starting with small, easy to scan objects, and working your way up to gradually bigger and bigger subjects.
By the way, I had to look up what midgies were- I thought "maybe seagulls?". Nope! Haha
Man this is so great thanks so much, Are you still going to make the rest of the series?
Thank you, John! Yes, I have the next two videos scripted, and should have Part 4 uploaded sometime this month. I hope you will like it!
ClassyDogFilms I'm sure I will! I've been interested in photogrammetry for a personal project I'm currently working on in Unreal Engine. Your videos have been an invaluable resource, your great sense of humour makes them light and easy to watch and come back to. can't thank you enough!
Thank you, that's very encouraging to hear! I do my best to keep the videos informative while still being fun to watch. The script for the current video has gone through 11 iterations already, it was a real challenge!
I think the BGM starting from 6:50 is great.
Can I ask the music?
Sure! It's called "Ripples" by Kevin MacLeod aka Incompetech.com. You can get it for free on his website.
This is the funniest tutorial i have ever seen 🤣🤣🤣🤣
Thank you, I'm glad you enjoyed it! Your truck tracking shot is really good, btw!
I love your videos. This one made me LOL so hard....OCCLUSION HELL
+Mark Lapasa Thanks so much, Mark! I hope the next one will be just as enjoyable.
ClassyDogFilms I am looking forward to part 4!
How about using a camera with a 3D mode on? Is there a benefit?
I've never used a camera with depth sensors yet, and I'm not sure if any of the photogrammetry software supports any of them yet, but I'm sure in the future they will become more supported!
Amazing work! What camera do you use for your scanning?
Thank you! I still use my old Canon T2i. Maybe one day I'll be able to upgrade to a bigger camera.
Sir, you are awesome!
Thanks for these great videos. Question: Do I need to buy the Pro version to do environment scanning or will the Standard version work. Big price difference! Pros / Cons
Thanks! The Standard/Basic version of PhotoScan should work for just about any type of project, environment scanning included. The pro version comes with advanced stuff that I honestly don't even understand half the time, but it's intended for top level scanners who need the very specific tools to refine their results. But I think most of us are unlikely to ever need those extra tools, so the basic version should be enough!
Fantastic. Thank you for your fun and informative channel.
Quick question. Do you know if it is possible to stitch together drone photographs taken from different elevations? IE would it be possible to combine low flying images taken underneath tree canopy and combine them with images taken at a higher Ie 250 ft elevation ?
Thanks again for sharing your expertise.
Hello, Gregory! Apologies for the delayed reply. I believe you shouldn't have a problem with changing the elevation like that- the only thing I would recommend avoiding is any change in focal length while shooting, since I believe the newer versions of Metashape (if that's what you are using) don't like aligning multiple focal lengths into the same scene. Having said that, I would recommend shooting a small test scan just to get an idea of what kind of results you might expect before shooting a larger area. I hope that helps!
subscribed !!! want to ask Do i need a camera with GPS funtions ? to align photo ? i am buliding UAV for mapping now i only lacking of camera.... any reply in this will highly appricated... i am looking again how to measure distanct like scales tools .... normally i export to tiff and mesure using QGIF ... any solutions that i can just do everything in a agisoft
+Uni Productions Thanks! I know that GPS data is not necessary for large area scanning, but it can help. I have never done any of it myself, but I know many people have. I recommend checking out the 3D Scanning Users Group on Facebook: facebook.com/groups/1439036619645915/
There are some very talented scanners on there who should have more specific answers for you relating to that field. I know there are dedicated tools in PhotoScan for georeferencing and stuff like that.
Love it man! Keep it up!
+GroovyV Gaming Thanks very much! I've already started work on the next one!
3rd tutorial and equally bit as good as the preceding two, put me right on a couple of things. When will pt4 be out please?
+Gary Whaley Thanks, Gary! I hope to have part 4 out within the next 2-3 months (I'm building a new computer to be able to generate higher quality scans, so that's adding a little time to the process). I have a lot of tips I'll be covering in it. Thanks for watching!
Holly sht that was some smooth talking
Thanks! Hopefully even smoother talking in the next one!
Now I also want to do an awesome tree scan! Damn you! It is night! I cannot shoot photos!
Damn now I want to scan a bonzai, but mine is long dead!
This video gives me too much inspiration!
Maybe you can find a friend with a bonsai! Or maybe you'll find something even cooler than you can scan, now that you're thinking about it!
Great videos, funny too ;) What about focus? Do you refocus prior to every shot with AF or set it manually and stick with it?
Thanks, Tzur! If I'm shooting handheld I'll generally refocus each shot with AF. If I'm shooting on a tripod, I usually set focus manually and refocus when enough movement has occurred. It's tedious, but sometimes AF is inaccurate.
Very nice and didactic&fun style of the video! Thank you for sharing! I am actually having troubles scanning a big tree, it seems the program don't recognize part of the pictures as there are many big roots on it.I saw some people use simple stickers to help the program identify better the scanning.What do you suggest? Thank you in advance :)
Hi, Jose! Certainly, you can stick markers or other things into a scene to help the software better identify areas, but I would be surprised if this is necessary for any part of a tree. Would it be possible for you to share an example image from the shoot? It may be that the tree roots are underexposed a little too much, since darker areas tend to get ignored.
@@ClassyDogFilms yes!Is there any email where i can send it to you?
Feel free to send it to this email account, classydogfilms (at gmail)!
First of all, awesome info!
Second, you remind me of a kinder version of Ron Swanson :)
Haha, thank you! I've actually never seen the show, but I do know who that is!
Hi. This is great stuff! Are any of these environments available for downloaded so I can view them within my VR headset? I'm particularly interested in a forest or woodland environments, something with vegetation.Thanks!
Hi, David! Unfortunately, I think I deleted all of them years ago to regain harddrive space (I really only shot them for the tutorial), but I will try to do some more in the coming year and make some of them available for free. I do have some free tree textures on my Gumroad page if you ever need those. And I know The Terrain Domain also has some freebies that you might find interesting. I hope that helps!
@@ClassyDogFilms Thank you!
Do you think I could scan my body into a playermodel? I could stand in the t-pose and rig it after. I'm using the software so I can make a videogame. Houses too, would it be hard to do houses?
You could definitely do both bodies and houses! I'm working on the next PhotoScan guide right now, which will include how to scan buildings. For scanning your body in a T-pose, it will help if you have something solid to hold onto, like poles or something, to keep your hands from moving too much.
Such a good video. I've just today started looking into this. Considering it's reasonably easy to obtain tons of scans, you'd think there would be a few resources to download free scanned objects to try out/take a look at. I really can't find any.
+cr0uchingtiger You're right, there aren't! A fellow scanner, Daniel Morrison, has a website he uploads a lot of scans to. Here is the address: www.remnantstudios.com/freebies
How does this work if the environment changes? Like let's say I take a bunch of pictures of a model railroad while the trains are running? Will the software just error out, or blur it together, or come up with a result that makes sense?
It's hard to say what will happen, as I've never tried it myself. As long as most of the area in the images is static and non-moving, the result shouldn't be too bad. I recommend trying a small test first if you can. For greater control of the scan, you could mask out the train and any other moving parts. Or if you can shoot with a tripod, you could take multiple exposures from each position, and just combine them to remove the train. But only attempt that method if you can shoot with a tripod and preferably a shutter release, as any camera movement will ruin it. Masking may work just fine, if it's even necessary.
Sooo I dont know if you're around anymore, but would be awesome if you had a answer.
What is a optimal distance towards objects? Is there something you should watch out for?
what is a good CHEAP equipment for poor VFX Indies to go with when
they're trying to do air shots? I heard you require a closing time of
1/60 or a really high stability to get good pictures. This might be
difficult to acquire when a drone gets hit by wind. Furthermore
occlusion and so on gets into this.. so do you have some tips
recommendations or tuts?
Hi! You know, I've still never used a drone, so I can't really give much info about them. It might be a case where you have to spend a bit of money to get one that can get the job done in less than ideal conditions. But I really can't say without having any experience using them.
However, I do know a good deal of people on the "3D Scanning Users Group" on Facebook who use drones in their work, with great results. I would recommend asking there, as they're sure to have some helpful suggestions!
It is possible to have subtitles ?
Also it would be nice to have direct links in the video or in the description
darty367 Those are both excellent suggestions! I will add all the links into the description tomorrow, and figure out how to upload subtitles to this video very soon!
i just started using the software and found this software tutorial really helpful. Are the images required to be geo-tagged too ? How can I measure / add scale to the pictures and the final model that is prepared?
Thanks! No, your images don't need geo tagging, but I believe you can use that in the Pro version for more accuracy on big areas. I've never tried measuring or adjusting scale, but there is a really great FB group that can answer that. Just search for "3D Scanning Users Group". Hope that helps!
Great Video and fun, too! Thanks a bunch for making it.
I have a question concerning post processing scans. I came to use realityCapture,which is a great alternative for photoscan. It is pretty fast even for large amounts of images and I've heard it beats photoscan so you might wanna give it a try some time. Anyway, it produces pretty large meshes. It does have a simplification tool, but not a very sophisticated one. I am looking for some proper software to remove artifacts, smooth parts of the mesh, remove complexity where it isn't needed and the like. What do you use for post processing and what can you recommend? Currently, I work with Blender but I feel there must be better options.
Again, thanks for the fantastic video.
Cheers
Ole
Hi, Ole! You're right, RealityCapture is a great program. I hope to try it in the near future!
I don't have a lot of experience outside of Blender, but I know many scanners like to use zbrush. It can handle those big meshes easily compared to Blender. It is a bit of money to purchase, but if it can fit your budget, I'm sure it could pay for itself quickly in time saved. I intend to buy a license myself next year.
Thank you for the kind words!
ClassyDogFilms thanks for the reply! I'll have a look at zbrush. Seems to be a good hint.
Blender can reach its limits quickly and nothing is worse than a crash after an hour of tedious work on a huge mesh. Zbrush would pay itself via all the equipment I don't smash in frustration :)
Hope to see more of your tutorials in the future.
Best, Ole
ClassyDogFilms By the way, what do you make of googles project tango and the Lenovo phone that works with it. Those seem to do a decent job of photogrammetry in real time on a mobile device. Do you think that can compete with a DSLR photogrammetry result? Probably no way to tell yet, but I am thrilled. Should be available this year
I know what you mean, just importing a huge mesh can takes ages in Blender. And I have heard about Project Tango, but I haven't really looked into it. I do think that DSLRs will still give the best results for a while, due to their resolution (especially when using the huge MP cameras), but I'm sure the real time stuff will catch up fast in the coming years!
Hi Classy Dog, nice 'tache. I am shooting 360 and VR - thanks for an awesome and fun intro into 3D scanning :-)
+Luke Woods I'm glad you enjoyed it, thanks for the kind words! 360 and VR is an exciting field to work in, lots of opportunities in there!
Hey, Ive been making short films for a little while now but its been with a small handheld camera corder. While it got the job, I want to get a DSLR to be able to get better quality, change lenses, focus better, ext. I would like your opinion on a DSLR that costs under $400 that can get good video. BTW I'm not opposed to getting a used camera since this is my first DSLR. Thanks
Jon Parizo Hi, Jon! I would recommend looking for a used (but well taken care of) Canon t2i or t3i. If you want a flip-out screen, the t3i is the better option- otherwise the cameras are about the same. I bought my t2i new back in 2010, and it's still the only camera I use for both photos and video.
Some people may tell you it's not good enough, or if you want to scan that you should get this or that- but a cheap Rebel dslr gets you the most bang for your buck, and is an excellent camera to start with. You can find some good deals on ebay. If you have anymore questions, just let me know!
ClassyDogFilms Thank You, this really helps!
Jon Parizo Glad to hear it!
Where's the second half to this awesome video series? Part 3B Manmade structures?
I'm expecting to have it out in January (currently busy with a couple other videos). But the script is complete, just waiting to have time to shoot it!
Fukk, this is supposed to be a lesson but instead I'm cracking up at your jokes. Thanks for the tut!
Thanks, Victor! I hope the next one will continue the trend.
Hi I've not managed to get the quality u r getting on aerial drone scans ? I have apps 200 photos for a plot of land shot from magic pro . It's ok ish but just not like any I am seeing online ? Any ideas thankyou
Hi, Trevor! I've still never used a drone to shoot scans myself, but I'll offer some guesses as to what might improve your drone scans. It might be the time of day: Are you getting a lot of light for a good, sharp exposure on the camera? It could also be your subject matter: stuff like castles and mountains are probably a lot easier to get good looking scans than a plot of land will be; not just because the former is more interesting, but because their features are much larger, and therefore easier to capture from a distance. If you're scanning dirt, you might have to get closer and shoot many more photos. Those are just some ideas, feel free to upload a sample picture though if you still have trouble!
hey. got question for you. is it good to produce 3d images using images got from video, like action camera? if so, can you suggest methods/ideas to get great 3d images from it. thank you.
Yes, you actually can get good models from video. I'll talk more about this in a future video, but generally you'll probably want to shoot a little closer than you do for still images, because the compression in the video will erode details a little bit. The higher the bit-rate you record your video at, the better quality of the scan will likely be. For example, the Panasonic GH-series of cameras will give a decent result due to allowing you to shoot at higher bit-rates than most similar cameras. I would suggest doing a test run and seeing what kind of results you get with the camera you have- that will tell you if you need to shoot closer (or slower).
You rock ! Like a scanned rock :)
maayaa77 Thanks! You might say I "wood" be hard pressed to find a better compliment. Get it? Like the wood of a tree that was scanned?
Ah, yours was better... Thanks for watching!
Great video!
Thanks so much!
great video, very informative & funny! I have yet to experiment / use agisoft photoscan, but I am looking forward to it. What potential issue and success do you see with taking photos with a 360 degree camera (ricoh theta)? There may be worst photo distortion than a fish eyed gopro, but maybe theres an easy fix that'd result in better & faster environmental photo coverage. Thoughts/ideas?
+Dogma 360 Media Thanks! It's tricky to say, as I've never tried it myself, but I do believe it's possible to get some kind of result from 360 degree images with PhotoScan. I can't say how good the quality would be- as you know, the wider the field of view of your images, the fewer images you have to take, but the lower resolution the details become. Having said that, you could always combine 360 degree shots with normal photos to find a balance that works for you.
The other great thing about cameras like the Theta is that you can capture IBLs when you're scanning to aid in de-lighting your textures later on! I hope to cover that in the next tutorial.
i love your videos! i learn stuff and laugh my ass off.
Mason Menzies Glad to see you found the videos, Mason! Your work in Blender is great!
ClassyDogFilms Thanks m8. hey, what camera would you suggest for 3D scanning (preferably one that can shoot in raw) that's under $500?
Mason Menzies I myself still use my Canon t2i, which I bought new back in 2010. It shoots RAW, and can be found on Ebay for around $250 USD I believe. There are newer Rebels available as well, such as the t3i with a swivel LCD screen (can be very helpful), but other than that they're pretty much all the same image quality. If you're on a budget, I'd look for an older Rebel model rather than a newer one.
Mason Menzies And when I say a "newer" Rebel models, I mean like the t5i or t6i. I'm sure they're slightly better cameras, but it just wouldn't be worth the extra cost of buying them, especially because they're probably way over your budget.
I've been using my iPhone 6s Plus to scan object and I've been getting some ok scans but when apple allowed raw image capture on iOS 10 using adobe lightroom on my phone I was able to capture sharp clear images. I've ran into a bit of a problem tho. Agisoft photoscan recognizes the images but it doesn't process the data correctly for some reason. Tiff don't work so I was forced to export as a jpg. But I have to say the image quality was still higher than the jpg before. Images scans where 3 times better.
That's really encouraging to hear! I've never tried it myself, but I think phone cameras have finally caught up to be able to generate decent quality scans. I bet if you made a short tutorial about it, a lot of people would be interested to see it!
Thanks I think I actually might make the tutorial.
Hey folks, more photogrammetry tutorials here:
www.vfxforfilm.com/copy-of-lah-101-houdini-live-action
you can make small things look big! Lmao I lost it
+Potatowarrior 13 Glad you enjoyed it! I try to make the tutorials fun to watch.
In that you certainly succeeded!
Also great video though, one of the best out there on photoscan.
+Potatowarrior 13 Thanks! I hope to have the next PhotoScan video up in a couple of months, just saving up to build a new workstation first. I have some special things I want to show in it.
Awesome! I'm looking forward to it!
I'm interested in applying this using a drone with/or a camera. Do you have software you recommend the most? Is there anything that makes masking super easy for when you have to do dozens or hundreds of images? Final question- do you do anything with copyrighting the things you develop? Some of the demos you showed were incredible- I imagine there's people who would love to make use of them either for film or printing- do you license some of them or no?
You can definitely get good results with a drone. Generally, I would recommend either Agisoft PhotoScan or Reality Capture. There are other programs out there, but those two are very well known and give excellent results. For masking, I know you can create Photoshop actions to help speed up the generation of masks. How you decide to create the action depends largely on images themselves, but you can use things like luminosity and color to create selections. I think you can even make selections based on sharpness.
And I've never licensed or copyrighted any of the scans seen in the videos, but I also haven't saved any of them, either. They got deleted years ago in order to free up space on my old computer. But in the next video, I'll be making the scans shown available on Sketchup for free download!
Sorry, I meant Sketchfab. Not Sketchup. I get those two mixed up all the time.
Classy move! Open source makes the world a better place. Thanks!
awesome videos man
+Tyler Gibson Thanks, Tyler!
Hi ! When you take your several photos of the subject, is it possible to get closer to the subject without altering the lens configuration for more details, or we have to stay at the same distance all the way around the subject ?
You know, I'm not certain, but it may depend on which photogrammetry software you're using. I think some don't care if you change the lens (such as the focal length) while shooting, and other do. But I don't worry about changing the focus, I do that all the time and never have problems with it. I don't believe maintaining the same distance from the subject really matters, as far as getting a good mesh result.
@@ClassyDogFilms Hi, thanks for taking time to answer me.
I was not saying chasing the focal, I meant , just getting closer to the subject.
Great Video
Thank you! I just quit my job, so there will be more videos this coming year.
Brilliant! Thanks. :)

What software do you use for scanning? Great video by the way.
+Peter Delgado Hi, Peter! I use Agisoft PhotoScan for the actual 3D scanning, and I use Blender to render out the animations/turntables.
