Summary:Light sources of different colors, such as additive or subtractive primaries, are provided within a camera body to expose the film to the colored light as an auxiliary exposure. The auxiliary exposure is imparted to the film simultaneously with, before or after the normal exposure at the time of photographing. The light sources can be, for example, LED's which emit different colors, or a combination of a white light source and color filters of different colors provided in front of the light source.
