There is disclosed herein a compact flash camera or flash unit including a red-eye reduction lamp on or near the front of the camera to shine light toward the subject being photographed to minimize or eliminate the red-eye problem. The camera includes a conventional electronic flash system, along with a flash ready light to provide an indication when the flash system is sufficiently energized to fire the flash tube thereof. The red-eye reduction lamp and the flash ready lamp, whether two separate lamps or a single lamp, are turned on and off together so that the red-eye reduction lamp is on and emitting light toward the subject to be photographed whenever the flash is ready to fire. This system minimizes the care the photographer needs to exercise when composing and taking a photograph. The principal applies to both built in flashes and detachable flashes.
