Some parts of the photo are overexposed and some parts are underexposed. What should I pay attention to when shooting? How to avoid it?

The phenomenon of partial overexposure and partial underexposure is due to the excessive light ratio in the shooting environment, sometimes caused by backlight shooting. It can be adjusted by reducing iso sensitivity, increasing aperture, and applying flash or reflector to fill light. When shooting, pay attention to the metering mode of the camera, spot metering or central key metering (the camera is in focus when the shutter is half closed, and spot metering is close to the focus of the camera, so exposure compensation cannot be carried out in this mode. Because the subject is mostly dark when shooting in backlight, you should try to use flash and reflector to make up the light, which can reduce the contrast of light. Pay attention to avoid direct glare, and the strong top light at noon is not good for the photographer.

As for the exposure of different points and different degrees, I have never heard of it. The current camera is not well estimated. In addition, it can be said that it is also distorted.
