What can a photographer do besides taking pictures?

Well, your pain is understandable. In the business model, fixed composition, unchanged scenes, lighting, makeup and even posing are all handled by special personnel, and photographers have become masters of shutter. I think under the present circumstances, the photographer's purpose is to survive, so try to open his own studio, from small to a studio, a camera, slowly to large-scale, don't be discouraged, set a goal for yourself, and then work hard slowly. As an amateur photographer, I can only comfort you in this way.
