I just want to ask, do photographers usually prepare their own props?

Depending on the demand, if it is a cosplay class, basically coser brings its own props, and the photographer only brings the equipment needed for shooting.

If it is a photography class, they usually communicate in advance. If there are any props that may need to be used, both parties will bring some as appropriate.

If it is a photo studio, it is basically the photographer's belt, and the subject can also bring some as needed.
