Sounds like a real-life Pokémon Snap. You should add a digital professor who gives you points based on how good your recent photos are. (Size of subject in photo, focus, in-frame, and if the animal is doing something interesting.)

That doesn't work well even when it's the only game mechanic and everything else is designed around making it work.

It's not likely to work well on actual photos of actual wildlife.

That just adds to the fun.
