What else should photographers learn besides ps? Because I taught myself, I can't find my way now. Now only, camera shooting.

Photography is the art of light and shadow, so we should understand light, including natural light and lighting. I also know composition, color and plane aesthetics. Photography is also divided into portrait photography and landscape photography. Portrait photography should know the structure of human body and be good at capturing the most beautiful angle and expression of people. Landscape photography should know how to use natural light and be good at recording three-dimensional scenes in a plane way. Ps is just a link in the art of photography. It is the re-creation of photography and the re-processing of the original.
