The difference between perspective and exposure

Perspective is X-ray, and exposure refers to the light emitted or reflected by the object being photographed.

Perspective means that the X-ray tube continuously emits X-rays to penetrate the human body for a short time, and the perspective time is related to the heat capacity and other properties of the X-ray tube. You can dynamically observe human X-ray imaging in a short time by stepping on the exposure pedal. Similar to video. Exposure refers to the amount of light entering the lens and shining on the photosensitive element in the process of photography, which is controlled by aperture, shutter and sensitivity. It also means that something is exposed or exposed.
