Zusammenfassung:	An automatic exposure control in which the simple trigger circuit determines if the light level is sufficient for normal exposure of if the fill in flash is required. If the last bulb of the flash card, or flash cube has been used then the exposure control automatically resets to normal exposure. The system enables exposures to be taken fully automatically if there is sufficient illumination. If the fill in flash is not available then the camera can still take an exposure providing the light level is above a minimum threshold.
