What is Exposure (photography)?
{{redirect|Overexposed|the music album by Maroon 5|Overexposed (album)}} In [[photography]], '''exposure''' is used to mean two things. [[Photographic film]] or [[sensor]]s have a certain senitivity. That means that a certain amount of [[light]] needs to be able to reach the film or sensor, before the image is correctly exposed. It is measured in [[Unit of measurement|units]] of [[lux]]-[[Second|seconds]] (symbol lx ⋅ s). An exposure can also refer to a photo exposed that way.
