Tell us about the differences and relationships among photographers, post-teachers and colorists.

Photographers take pictures or videos. Another example is later wedding photography, including color matching typesetting, video editing, color matching (regardless of sound) and so on. Take photography as an example, the core is the photographer. A photographer has decided the tone, style, composition and content of this photo. The colorist only completes what the photographer did not finish in the early stage, which is a supplement to photography, and typesetting and editing are re-creation. But the general idea is decided in the early stage, so the photographer accounts for the vast majority of the quality of a photo, and the later stage is not good: first, it is really bad, and second, it is impossible to understand the photographer's intention, which may be a technical problem or a level problem.
