Are all photographers' works post-processed?

These are all "as the case may be" questions. The concept of owner is also very general, and different owners handle photos in different ways. For example, fashion photographers prefer post-processing and computer processing.

But as an art photographer, it's very bs to process it with a computer. They like hand-made darkrooms, (so do I)

If it is a news documentary, there are some that are processed and some that are not. Processing simply adjusts the light to be brighter or darker. In addition, the camera is the most important thing in photography. Masters do not become masters by the high quality of cameras, but by their ideas and perspectives.
