Questions tagged [exposure]

Exposure is the total amount of light allowed to fall on a sensor or film during the taking of a photograph. This is determined by the exposure time (shutter speed) and amount of light admitted (lens aperture). Today, sensor/film sensitivity (ISO speed) is often also considered to be part of exposure.
