Is a small amount of PS processing allowed for photographic works?

Photography competitions are generally divided into several categories, such as:

First, the documentary category, also known as the recording category, is not allowed to make major processing except for appropriate adjustments such as screenshots and brightness, and of course, it is not allowed to increase or decrease the content at will.

The second is the art category, which allows suitable PS post-processing and even appropriate re-creation, but generally requires truth. Especially in creative and image experiments, you can do most of the PS operations you can think of, as long as you achieve your goal.

Third, the business category, this category can be any PS processing.

I hope the above answer will satisfy you.
