Can the photo contest works be PS-processed?

Looking at the requirements of the competition, generally speaking, photography competitions allow limited post-processing, but there will not be too much post-processing.

What does this "limited" mean? Generally, adjustments are allowed in the following aspects:

1, white balance correction

2. Adjustment of color scale and color curve

3、HDR

Step 4 stitch together multiple photos

Step 5 cut

In fact, most of the so-called post-processing mentioned above can be realized in the darkroom in the film age, so most photography competitions do not shy away from these techniques. The above applies to most photo competitions, but some competitions strictly require you to go out directly or allow more later stages, depending on the rules of the competition.
