Abstract
A camera for use with photographic film. The camera has a body and an exposure system disposed in the body for exposing the film on a frame-by-frame basis. The exposure system includes an exposure opening and a shutter mechanism. The shutter mechanism is momentarily displaceable from a closed state to an open state. A light emitting diode 14 is disposed in the body for directly illuminating one or more positions on the film. Momentarily closeable, normally open contacts 16 are mounted in the body. The contacts 16 are closed for a time period of from about 0.05 milliseconds to about 10 milliseconds, or preferably from about 0.05 milliseconds to about 2 milliseconds, when the shutter mechanism is in the open state. A circuit directly connects the battery unit 18 to the light emitting diode 14 when the contacts 16 are closed. During contact closure, a battery unit 18 powers the light emitting diode 14 at a current level beyond continuous use operating limits of the light emitting diode 14.
