What's the difference between turning on the light and not turning on the light in the studio?

When shooting in the studio, it depends on what kind of light is used. When shooting with a flash, it doesn't really matter whether to turn off the basic indoor lighting (usually tubes or energy-saving bulbs). If shooting with a constant light source, it is recommended to turn off the lights, mainly because the color temperatures of different light sources are inconsistent. So, if you can, you'd better turn it off, which makes you look particularly professional.
