What are the requirements for photographic works? Shouldn't software post-processing be allowed?

Exhibitions and entries can be properly PS-processed, but generally only the color scale, curve, contrast and saturation can be adjusted. Creative works allow more PS, focusing on the content of the works, which is stricter than the entries, and it is not allowed to add or delete any element content in the photos.
