Abstract
An external light integrating circuitry connectable over two-wires to a flash control circuitry, for causing automatic disabling of an internal light integrating circuitry connected within the control circuitry. The external integrating circuitry receives power over the two wires and transmits light integrating information back to flash termination circuitry within the control circuitry. Camera shutter contacts are connectable with the external integrating circuitry for transmitting a flash initiating signal via the two wires for initiating the photographic flash.
