A system to measure the colour and brightness of the scene to determine the exposure. Evaluative metering meters the overall scene in multiple sections in the viewfinder. It determines the correct exposure based on the subject's position and lighting conditions. Centreweighted metering weights the metering on the centre. Partial metering weights the metering on a specific area. And spot metering meters a very small area of the scene. Also referred to as: evaluative metering, centreweighted metering, partial metering, spot metering
