I understand the need to clean or enhance (not modify) a photo for easier identification. Lighten; Brighten, etc.
I also understand the need to prevent the potential creation of AI-generated organisms.
My suggestion: Add the original as a 2nd photo. This way, any person can then see the original and know that the manipulation is purely for clarity purposes.
Further, if necessary, add a comment explaining the reason for the enhancement. (E.g., Leaf enhanced to highlight venation.)
I would like it if any of my observations were downgraded to Casual; I get a notification regarding this. This way, I can defend my decision and not discover it months later by chance.
