Photography nonsense: p, Av, m, which is higher?

P is suitable for snapshots when the lighting environment is complex, some street shots, etc. , and it is used when you don't have time to slowly adjust the parameters;

The application environment of AV is similar to that of P, and it can be used when a certain aperture needs to be deliberately used.

M is suitable for professional photographers, can better control the exposure and depth of field of photos, and adjust parameters according to their own shooting intentions, which requires rich shooting experience.
