Photo studios are places intended specifically for conducting photo sessions. Spaces like these are often decorated in a particular style or have several different interior zones. Photo studios should be equipped with special interiors and backgrounds. Pay attention to how the studios are described, and to whether use of equipment is included in the booking price.
