Definitions for "Exposure meter"
An instrument for measuring the intensity of light so as to determine the shutter and aperture setting necessary to obtain correct exposure. Exposure meters may be built into the camera or be completely separate units. Separate meters can sometimes measure the light falling on the subject (incident reading) as well as the light reflected by it (reflected reading) ; built-in meters measure only reflected light. Both types of meters may be capable of measuring light from a particular part of the subject (spot metering) as well as taking an overall reading. Commonly called a light meter.
A device used to measure the brightness of the subject or illumination level at the subject position. This information and the film speed can be used to determine appropriate camera aperture and shutter speed settings.
