Definition: The quantity of light allowed to act on a photographic material; a product of the intensity (controlled by the lens opening) and the duration (controlled by the shutter speed or enlarging time) of light striking the film or paper.
Definition: 1. The act of letting light fall on a light-sensitive material. 2. The amount of light that passes through a lens (in either a camera or an enlarger) onto a light-sensitive material (film or photographic paper) to form an image. In the camera, too much light causes overexposure - this makes negative film look too dark and reversal film look too light. Underexposure (too little light) has the reverse effect. In enlarging, overexposure makes a print from a negative too dark and a print from a slide too light. Underexposure has the reverse effect.
Definition: product of the intensity of light and the time the light is allowed to act on the emulsion (I x T = E).
