What's the use of the model behind the photographic lamp?

Model is a modeling light, which means that the light bulb in the middle is not a flash.

The flashing button is a photographic light with a lightning icon. I really haven't seen the rest carefully, and I don't remember what I used when I took pictures. These are the only things that can be seen on Taobao. If there is a picture, it will also show that each button is used for explanation. .
