My from midjourney ai generated pics got all rejected. Can you help me to understand why? Do you know a tool to easily mass modify the pics?
You're missing the point. You're expected to personally use you individual skill to make the very best work. Not automate things. Adobe don't need you to work faster. So YOU have to check the composition and detail. Not have the cat's ear cut off, or weird split nose. Not have a cat with owl eyes and weird feet. Not have wood too dark to see - a photo would be rejected if that underexposed.
Sorry. There is no magic bullet that can adequately fix all your AI problems.
Some problems can be fixed with additional text-prompts and repeated diffusion runs but most problems have to be manually edited by an artist who can paint & draw. Untrained AI is really bad at ratios, perspectives, geometry and fine details. That's why most of it is unfit for commercial use.
I would let these go and work on more promising assets. Focus on quality, not quantity.
