You have saved me hours of hair pulling investigation. Thank you so much. I had been wondering if my photos would be good enough for printing and you helped me understand the whole ppi and dbi standards. Much appreciated!
This is what exactly I needed to know and you did a great job explaining it. Thanks!
Your channel is a goldmine of information! I was clueless about how to approach printing a photobook, there is so much to learn from you. Thank you so much for the time and effort you put in those videos.
What a great explanation! Thank you for this video. Your explanation was easy to understand.
It is a very clear and helpful video. Thank you so much!
As others have said, you explained the print requirements in a more easily understandable way than many others have. Thanks!
EXCELLENT explanation. Thank you.
God bless you! Thank you, your rant was so helpful and I get it now.
Finally. Someone who answered my question. Everyone talks about ppi dpi and resolution but I had yet to see a video that did the math for the output. Thank-you.
Thank you very much for this.. i loved that u dont have unnecessary information..
Well presented! I was worried that you were not going to cover "viewing distance." Thankfully, I watched until the end and you finally talked about this key factor.
In my experience, large poster prints or "wall art" look spectacular when viewed from several feet away, even when their pixel density is only 100 ppi.
For the most part, you did a very good job using ppi (instead of dpi) in its proper context. You did slip up on three occasions. I would have corrected these errors in post-production before uploading to TH-cam.
In today's world of AI (2024) images with very low pixel densities (eg: 50 ppi) can be "upscaled" using specialized AI (Artificial Intelligence) algorithms and the resulting files can look great when they are printed at home, or by a commercial printer.
One final point... most commercial printers use high-quality hardware for printing (ie: an Imagesetter) that have an ink print density of 2500 dpi.
Great video ! Very clearly laid out. I’m annoyed its taken me this long to find your channel. will defiantly look at your other videos, keep up the great work.
Welcome aboard!
Wow that actually made sense,Thank you for that 👍🏼
Thank you. Excellent video. Strong content and good presentation skills. 🎉
complete and perfect video, appreciate it
Very important information, thank you.
very well explained. thank you!
Very very helpful video.. all i want to know is in here.. thank you for this. Very detailed and clear.. ❤
Love your video. Trying to put together my wedding photo book and this really helped. Also your video on comparison between Shutterfly vs Photobook WW, vs etc.
Thank you! It is very helpful.
Thank you so much for this video, I am publishing my own children's book, and I was having a hard time deciding what PPI I should use. Great video, thanks so much and have a nice day!
super amazing explanation..massive thanks
Thank you for this video!
Great explanation. Thanks
Great video! Thanks.
Very helpful thank you!
great video! Saved me so much time researching. Thank you a lot!
thanks for the explanation i subscribed
Very helpful, thank you!
Thank you so much, Solved so much confusion in a single video... Much appreciated!
Glad it helped!
what a beautiful video, Thanks a lot
Thank you for the good information
First time I've heard the output math explained. How simple that is. Thanks for that little gem!
Thank you so much!
Finally i understand, thank you much!
Thx ya for this. I was trying to figure out what's the long side of a photo. So I can make my submission. You wouldn't believe the video's in yt not explaining this.
You save my life ❤️
Brilliant video m8
Useful information for everyone :)
Thanks 🙏
Hey man, Love your videos.
I know this might be a silly question but I brought a camera that's shoots 25mp. I have some nice photos I want to enlarge. When I transfer the photos to the PC the dpi is 72
If I want to print a canvas 16x24 ( 40.5 x 61cm) would I make my settings on image size fit to custom and than width 16 and height 24 with a 300dpi to get the best photo print? Would I than do the same method for a smaller photo 7x5
Thanks in advance
It made perfect sense
Thanks
Thank you Guru. This video was very helpful. I am planning on creating an artbook on Blurb with BookWright (maybe). Right now I use "Gimp" to make and modify my images. If my images are very large such as 6000x6000 and I put it on a 12x12 page in a photo book, will the software have to down scale my image? Have you ever run into a situation where the image was too big for the page, which resulted in the image being pixelated?
6000pixel/12inch=500dpi. That's less than the 600dpi a good printer will do easily. So, actually, the software will have to interpolate.
Wow thank you, i'm working on a future print business, and thanks to you i realized that even with an A7RIII and its 42mp, it is not enough to print on A1 ! I am so surprised :o
It can still be printed. It's like he said towards the end, one will mostly be viewing the A1 size photo from at least 3 meters. So, a 170-200ish dpi would look just fine.
Very useful.
In metric system I use 100px per cm. Very simple and good enough.
Number of pixels is definition and resolution is a pixel density per inch or cm
I think you mean cm. 300 ppi is 118 ppc. mm is just not in the same order of magnitude at all
@@Brittow Yes I corrected it. Equivalent to 254 ppi, less than 300 but enough for photo paper, most printers...
Easy if I want to print 15 cm I need 15*100 pixels very easy when you use metric system.
What is the size you want isn’t 10x10 (a square) but at 12x16. Do you still only divide the longest side? Or do the short and long side have to be bigger than 300??
Great video! quick question though - If my printer prints at 300dpi, would there be any difference in printing quality between a photo of 350 ppi and 450 ppi?
really good video and explanations.
( just add some photos or images while you talk so we're not just looking at you all throughout the video)
Is it ok to upscale during export to meet the 300 per inch of the planned print size?
Hi! Have you or do you plan to review Artifact Uprising's photobooks? I am interested to hear what you think about their products.
I'm planning to but can't confirm how soon it will be.
I have a photography question. I am not a photographer but I want customers to upload an image. It will be reduced in size to fit on my product.
I don't want to lose resolution. Since the image they upload will be used to print on something. What is the software per say. I can install on my website that will automatically resize and embed pixels in a photo for it to be print ready.
Are you teacher? excellent video you made it so comprehensive. Thank you
Yes I am!
Thanks this is very helpful.
Can you please review once on viesus. It is a cloud based AI solution that enhances and upscales the images and it is also helpful in facial reconstruction.
You can easily find it by searching it in your browser.
Howzit bud, probably the most informative tutorial on the topic I’ve come across, however, I’m still having a bit of challenge wrapping my mind around a few processes. Let’s take a step back…I’m wanting to explore printing onto t-shirts using the sublimation process (sawgrass sg1000 printer). The part I need help with is this…let’s say my creative process starts with a simple Google search on the internet for any random image and I happen to find one, I would then go and “save as” onto my desktop. I’d then drag that image into photoshop or CorelDraw either directly for print or manipulate/crop it to fit the layout of my t-shirt or design. Now…I think I’m somehow missing a few crucial steps here in ensuring the saved photo of the internet (usually 72 ppi/dpi) is somehow print ready at 300 ppi/dpi. What should I be doing as typically I would want to print a larger image to fit onto the front or back of a blank t-shirt. Thanking you in advance 🙏🏻
In Google images, make sure to filter by HD, large or something like that. Or search for 4k images.
Or if you weren't actively searching for images and randomly found something on a website and it happens to be of low resolution, reverse image search that image and download the highest quality available.
In general, anything over a MB should have a good chance of looking alright. Anything under 400kb would probably look bad.
This video was very help, it could have been more helpful if you actually showed and examples of everything you talked about such as how to find the pixel of a photo
You mentioned aspect ratio and cropping. Did you have any other videos explaining that?
Did you ever find out?
Hi, very good description of dpi and resolution, but have you got any visuals about using apps to increase resolution? Any help would be welcome- Robbie
Many photo viewers and more likely photo editors should be able to do it but I doubt that will do anything. A bigger sensor on a camera usually has a higher resolution and ensures that a lot of light enters the camera. This light is the data. By increasing the size in post, we can't create any new data.
There are a lot of AI apps now that can enhance resolution. Some of them use computational pixels, they are not so good, others like Remini have amazing results but can only work on faces. So there are still physical obstacles to that.
I came here knowing nothing and after listening to your video, I think I know most of what I need to move forward. Your style of communicating information is excellent.
Here's my question, if you don't mind....
I am just an artist who wants to assemble photos as collage etc...not to sell, but to decorate my walls. After I learn what the resolution and PPI are for one of my photos, is there a mathematical formula for determining what print size would be appropriate for the photo? (i.e., the size where it would look best, as the photog. had intended it to look).... And if there is a minimum standard for the industry, how far above that could I go for a higher standard (if there is such a thing). Thank you so very much for your clear explanation.....Good luck to you! 💖
There is no need to go above 300 dpi, most people will never see a difference, especially not from a distance. For resolution, depending on the pixel shape, divide the length by 300 to see how big you can print. so If your photo is 3000x3000 pixels, 3000/300=10, so the biggest you can print is 10 inches
@@PhotoBookGuru ... Thank you very much! I really appreciate your getting back to me. As I referred to previously, you have a strong ability in clear communications -- your ability to get directly to the point is quite admirable !
I wish you the best of luck in your present & future projects.
I printed a metal print of a 20MP photo 36x24 inches, and the DPI is about 144, however it looks great hung up on my wall. A billboard by the freeway can be shot with 1MP.
What did you put as the long edge?
What does the resolution in the Finder app mean since there's no output size? The dimensions are the input size in pixels right? It says my photo resolution is 72 x 72, but if I use the dimensions and output size to calculate the PPI, it is over 300ppi. Thanks!
Yes, in finder you only see the resolution of the digital photo (input). That means nothing without knowing the printed size
I want to use old photos from my albums how do I do that. Do I just take photos of them with my digital camera? and if so do I just snap them and then edit on the laptop. The resolution does not have to be great as it is for a memory book I will put text with them.
Scanning them should be better.
❤
So do I understand correctly… more pixels equals more resolution? And what do you recommend to reduce grain? thank you for this video. I will watch it 10 more times so it can soak into my brain. 😂
Hi! I have a picture where the original size is 6240x4160 pixels. I'm hoping to do a 30x20 acrylic print, but I want it to be incredibly sharp and I know that puts it at 208ppi. In Lightroom, there's an export option to choose a ppi. If I export the image at a higher resolution than the original, will I get a higher quality print? Or can the resolution only be as high as the original file?
The resolution can only be as high as the original because newer information/data cannot be magically created. You can still upscale it tho, but I'm not sure what happens. There may be some use of algorithm to create similar looking pixels to the ones nearby.
That’s the fundamental question. If you want to print larger but your original doesn’t get you to 300 is it safe to upscale at export having used the formula of 300xinches of planned print size?
Hello I bought jpg files on etsy with a dimension of 2739x4108. I printed them 50 x 70 cm and they where quite clear. How do I know what pixel density my photos have? Can I influence them in the camera settings? Where do we see the PPI for our photos?
Divide the longer side pixels by the longer side print in inches, so 4108/(70/2.5)=146ppi roughly
Nice discussion, but what I would like to have seen were actual prints that represented different levels of pixel density-300, 200, 100 dpi, etc. Because after all, judgments about what is an acceptable print size are somewhat subjective. For example, I have made 30 x 24 prints from my iPhone 13 Pro, which at max has 4032 x 3024 megapixels. That works out to around 133 dpi. Yet, I don’t hesitate to hang such prints on my wall, and no one has ever suggested that they were lacking in resolution. And by the way, that megapixel count IS available on the smart, phone itself; one simply has to click the “I” (information) button that accompanies the image. No additional apps are needed.
How do you take a scan of a very small picture and enlarge it for print? Thanks!
If it's very small it won't look good much bigger because the scanner cannot enhance resolution but you can use AI apps like Remini to upscale
I really wanted to print some family pictures off my phone in size 12x12 but got the "photo may appear blurry when printed" and i want to know how to fix that. If anyone knows
You can't fix that. You can print is smaller or you can try to use an AI app that can enhance quality and resolution
@@PhotoBookGuru thank you ill try that
Thx, like ur videos.. But.. The garbage on small pics will be visible even more on big canvas no matter how far u stay.. So dpi plays even bigger role in big pics..
😊
Thanks for the information I didn’t know if you would be interested in doing a video of the free prints square Photobook it’s on £2.99
EDIT
you pay £2.99 if you have already bought a your free book for the month
I want to print a banner of 8.5x1.5ft what should be PPI?
300 ppi if you start working on a larg diam. Image
If you work with graphics and vectors then 300ppi. If it's photos, then 150ppi will be plenty for a banner, you won't find many photos with resolution good enough for 300 ppi at that size

Welcome!!
Wait. Google Drive compresses images?
yes

Photo prints dont require the same DPI as a photo press product. 125 to 200 dpi is fine for prints. If you are doing a book, digital press, no less than 250 dpi, 300 is better. 4 color offset, 300 dpi minimum.
In attempt to break a world record of the highest resolution photograph what advice will you give?
Not exactly “free” meta data apps; priced per month.
