I want to use a VR physical camera. What parameters should be adjusted in general? Is it different from ordinary cameras?

Generally speaking, VR's physical camera is more flexible than ordinary cameras. For example, if the brightness is insufficient, you don't need to add multiple values. You can choose the shutter, aperture and ISO of a physical camera (the principle is the same as that of a real camera, and you can operate well with a basic knowledge of photography). Generally, we will adjust the film door (mm) and focal length (mm) (these two values are the same as those of ordinary cameras) F number (aperture, the smaller the value, the brighter, and vice versa) and white balance shutter speed (shutter, usually combined with aperture to complete exposure, the smaller the value, the brighter, and vice versa) Film speed (ISO).
