How to evaluate whether a person is a photographer?

I think "photographer" is a kind of professional setting, which refers to people who recognize photography as a craft and work for it, and respect the art and value of photography. There are professional photographers, non-professional (amateur) photographers, and some people do photography part-time. Some institutions pay for their works or have contracts to prove that they are employed by an institution to complete photography projects and work, or their photography works win prizes in recognized photography exhibitions and competitions. These people can all be called photographers.

On the other hand, some people love photography very much, have certain skills or even skills, or are obsessed with photography and equipment. I think these people are photographers or amateurs (for example, Zheng Zhongji is a super player), but they are not photographers.

Sometimes, "photographer" is what people call a person when they take photos, but he doesn't necessarily take this as his profession, so he is not necessarily a photographer. Just as people who play basketball well are not basketball players, grassland boys who ride horses and herd cattle are not jockeys, and bread made at home is not a baker.
