  dcterms:description "\"Exposure\" reflects the extent of ionization events taking place when air is irradiated by ionizing photons (gamma radiation and/or x rays). In photography, exposure is the amount of light allowed to fall on each area unit of a photographic medium (photographic film or image sensor) during the process of taking a photograph. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region."^^qudt:LatexString ;
