Center-Weighted Light Metering

Most digital cameras use this metering mode. The meter reads the central area of the image where you're primary subject or object will be and also evaluates the light levels of the surrounding space to select an average exposure. Because this metering mode is 'center-weighted,' your subject or object must be somewhere in the center for the meter to read it. This metering mode sets the proper exposure for virtually all of the candid and casual pictures that beginner photographers take.
