In cinematography and photography, pre-flashing is the exposure of the film or other photosensor to uniform light prior to exposing it to the scene to be imaged. This adds a bias to the overall light input recorded by the sensor. It is sometimes used for artistic effects, as it can be used to add a colour cast to shadows without significantly affecting highlights. It is also used in fields such as astronomy to bias CCD image sensors into a linear region, improving their low-light sensitivity.
