[[Image:Ap8-KSC-68PC-329.jpg|thumb|''Apollo 8'' launch. The photo is a '''double exposure''', as the Moon was not visible at the time of launch (NASA)]]In [[film]] and [[photography]], '''double exposure''' is a technique in which a piece of film is [[exposure (photography)|exposed]] twice, to two different images. The resulting photographic image shows the second image superimposed over the first. The technique can be used to create ghostly images or to add people and objects to a scene that were not originally there. It is frequently used in photographic [[hoax]]es. |

If you are using an optical camera, it is easiest to have a self winding camera for double exposures. On automatic winding cameras, as soon as a picture is taken the film is winded to the next spot. Older cameras are great for double exposures. |

The problem with double exposures, is that if too much film is exposed over the 2 shots, the picture will turn out too dark. Medium to low light is ideal for double exposures. Also, it is important to use a tripod for double exposures. If the setting of the two shots do not line up almost exactly, you won't get the desired effect and the background will be blurry looking, as well as the target. |

Double exposures are not limited to just 2 exposures, but keep in mind not over exposing the film. |
|||
Another way to superimpose pictures is digitally, using a program like [[graphics editor|photo editor]] like [[Adobe Photoshop]]. Simply alter the opacity of the the two images and line them up over each other. |
