At present, in the market, customers are usually attracted by exhibitions and promoters (the purpose is to make a publicity to let more people know about your photo studio).
Or find a model to perform live,
Personally, I think the publicity of the studio is mainly to let people know that your studio is different from other studios.
Shanghai's Golden Princess is not a big-name photo studio in Shanghai. He does wedding photography. But their business is very good. Because they insist on a belief: how I will shoot for my clients.
Instead of letting the studio decide, the customer has the final say.
I hope it helps.
