The photo studio is to recruit a free labor force, teach you some skills, and drill by yourself, otherwise people won't bother to talk about it.

The training school is more professional, from theoretical knowledge to technical practice knowledge. If you want to develop in this field, you must have certain professional knowledge, which the studio can't teach.

To learn specifically, you have to go on a field trip yourself. It's not enough to listen to publicity or recommendations from others. Go to the field to see the teacher and listen to the students who are training.
