What does a photography studio that takes pictures of models make money from? Advertising or something? How much does it usually cost to set up a studio?

I'm not in the industry, but I know a thing or two. Take pictures of the model to see if it's a private job. If it's a private job, whoever takes pictures will pay. If it's a magazine model, someone must have asked the photographer to pay. I don't quite understand the advertisement you said. The first thing is to rent a shop. If you don't own a shop, you have to set the rent according to the location of the city and the location of the shop. Then there's another one. There are all kinds of lenses, such as background cloth, flash, reflector, shooting table, tripod and even shading curtains. These are all graded, depending on how you choose. A SLR camera, some two or three thousand, some tens of thousands, the lens is more expensive.
