I plan to open a photo studio next year and want to learn photography training. What kind of training should I do? What is the specific professional name?

Now I go to the studio to work, study at work, learn some practical things, and read books. Training is all about theory. I go to the studio to learn things, watch photographers take pictures, shape, look at repaired photos, talk about life skills at the front desk, the price and cost of all businesses, the use of equipment, and communicate with various customers.
