"metering mode" 的定义和意义

What is "metering mode"?

Metering mode is a camera setting that controls how the camera measures light to determine the correct exposure for a photograph. It analyzes the scene in different ways to ensure proper brightness. One method evaluates light across the entire frame, another focuses mainly on the center of the image while considering surrounding areas, and another measures light from a small, specific part of the frame. Choosing the right metering mode helps achieve accurate exposure and detail in various lighting conditions.
