Still, IMO this is a case of enhancement that gives you a certain
edge (this is how your vocab is limited when you post only in the gambling section

). Now whether this edge is allowed or not, @icopress has the sole authority over it.
I will say that it would have been a better defense if you had uploaded pics of the same pizza but I understand the practicality of it.
Not to mention that some camera features (specifically third-party apps) could have an auto AI enhance feature.
Good question about color correction. It is allowed.
Moreover, the user can publish multiple photos if he wants.. usually I choose the best photo for voting, and the order of displaying photos in the public list is determined randomly.
But definitely any pizzas without any identifying marks will be ignored.
