==Description==

In photography, '''exposure''' is the [[total]] amount of [[light]] allowed to fall on the photographic [[medium]] ([http://en.wikipedia.org/wiki/Photographic_film photographic film] or image sensor) during the [[process]] of taking a photograph. Exposure is [[measured]] in [http://en.wikipedia.org/wiki/Lux lux] seconds, and can be computed from [http://en.wikipedia.org/wiki/Exposure_value exposure value] (EV) and scene [http://en.wikipedia.org/wiki/Luminance luminance]  over a specified area.

In photographic jargon, an exposure generally refers to a single [http://en.wikipedia.org/wiki/Shutter_cycle shutter cycle]. For example: a long exposure refers to a single, protracted shutter [[cycle]] to capture enough low-[[intensity]] [[light]], whereas a multiple exposure involves a series of [[relatively]] brief shutter cycles; effectively layering a series of photographs in one image. For the same [http://en.wikipedia.org/wiki/Film_speed film speed], the accumulated photometric exposure (H) should be similar in both cases.[http://en.wikipedia.org/wiki/Exposure_%28photography%29]
