Question

Image size for AI

The Adobe guidelines says " ... meet the Adobe Stock minimum file size requirement of 4 megapixels. Use the Enhance tool in Lightroom to increase the original file size, but don’t go beyond 6 to 8 megapixels."

 

But isn't that a rather small image ..? I believe that images usually are almost 20 megapixels - e.g. 5.000 x 3.500 pixels? Do I misunderstand something?

    I normally upscale AI images up to between 6000 and 9000 pixels on the longest side. It CAN be done using the appropriate AI upscaling tools and following up with some additional sharpening methods in Photoshop (along with CAREFUL inspection of the result). If an image starts falling apart during the process and begins showing signs of softness, over-sharping, artificacts, haloing and other issues that are beyond the scope of being corrected in Photoshop, they are consigned to the trash. I figure it's a rare occasion when someone would require an image that is 9000 pixels wide, but virtually everyone knows how to reduce an image without the need of special software. While if someone purchases a 6 inch image and needs it three times that size, they may not have access to tools or expertise that would allow them to do so successfully.

    Hi Danielle. Thanks for a comprehensive answer. I've looked a bit at Midjourney and have found that the upscaling apps that work best also cost some money.

    You might want to do a search on YouTube with the keywords "PIXImperfect image upscaler." He reviews 7 upscaling platforms, some of which I believe are free to use. Not sure.

      Thanks for the usefull links, Nancy. But I was only interested to find out if 6 to 8 megapixels are not very small images.

      Most modern cameras shoot in 24-50 megapixel range, far more than what AI services can generate.

       

      You should NOT upscale a tiny image beyond a certain threshold.  2x linear resolution is about the best you can do with commercial Firefly in Lightroom as an example.  If you go much higher than that, you'll introduce unwanted distortion & artifacts.
