What is the meaning and function of the camera's zebra crossing?

Zebra crossing is a basic function of professional and broadcast cameras. Zebra crossing is a parameter of light intensity during shooting, used to indicate the amount of light entering the camera. Specifically, the camera provides a zebra crossing function to indicate exposure, which can be turned on or off. When the zebra display is turned on, zebra stripes will be displayed on the camera eyepiece screen. The more exposed the area, the more zebra stripes there will be. In this way, the photographer can know the exposure of the picture and control the amount of light by adjusting the aperture. Generally, there are two options, 70 and 100, which are set in the camera menu. If you choose 70, it will be determined based on the appearance of zebra crossings in the normal brightness area of ??the camera eyepiece. Choosing 100 depends on the appearance of zebra crossings in the high-brightness area.
