Partial metering is a camera metering mode that measures exposure from a small portion of the scene, typically around 10% of the central area of the frame. This allows photographers to prioritise proper exposure for the main subject while ignoring less important background elements.
Partial metering is especially useful in high-contrast lighting situations, backlit subjects, or when the subject occupies only a small part of the frame. By focusing the metering on the key area, photographers can achieve more accurate and controlled exposures.
