What is Multiple exposure?
{{no sources|date=May 2014}} [[File:Karlheinz Stockhausen par Claude Truong-Ngoc 1980.jpg|thumbnail|right|A double exposure]] In [[photography]], a '''multiple [[Exposure (photography)|exposure]]''' is when a single frame of [[Photographic film|film]] is taken more than once. This usually happens accidentally if the photographer forgets to advance the film. To prevent multiple exposures, most modern [[camera]]s will not let the [[photographer]] open the [[Shutter (photography)|shutter]] again until the film is advanced. It can also be used on purpose for [[special effect]]s, such as creating a fake photograph of a [[ghost]]. The resulting [[image]] will be a combination of all of the shots. Multiple exposures are not possible on [[digital cameras]], but the effect can be simulated with the [[alpha channel]] feature of [[photo editing software]] such as [[Adobe Photoshop|Photoshop]] or [[GIMP]].
