Abstract
A camera is adapted to support a flash device capable of functioning in synchronism with camera exposure operation when electrically connected thereto and of generating electrical energy and to transmit same to the camera when the flash device is in condition to flash. A display device is operable in one mode by the generated electrical energy and apparatus is provided to set the exposure condition and includes a switch operable when that condition exceeds a predetermined value. Apparatus are operable by the generated energy through the switch to activate the display device in a second mode in response to the setting of the exposure condition.
