ABSTRACT:
A means for use with an auto strobo unit for a camera of the type having an electrical shutter comprises a delay circuit in the auto strobo unit which circuit includes a capacitor and a resistor connected in series and adapted to cooperate with the X contacts of the camera, and a circuit connected with the delay circuit and producing a shutter closing signal. The delay circuit has a time delay which is equal to or by a given length of time greater than the illumination time interval of the auto strobo unit which is adapted to be connected with the X contacts, so that when an illumination is provided by the auto strobo unit in response to the closure of the X contacts, the delay circuit is triggered to cause said shutter closing producing circuit to produce a shutter closing signal or an under-exposure signal to close the shutter, unless it was previously closed, at the end of the illumination time interval or a given length of time after such time interval.
