Summary:PCT No. PCT/CH81/00100 Sec. 371 Date May 7, 1982 Sec. 102(e) Date May 7, 1982 PCT Filed Sep. 8, 1981 PCT Pub. No. WO82/01080 PCT Pub. Date Apr. 1, 1982.A camera control device (21) with means for electrically controlling the shutter of a camera and for setting and displaying exposure time and aperture is electrically connected to an electronic exposure computer (22). The latter contains electronic circuitries for the logic operation of exposure parameters which shall be input and output in the form of coded digital signals. In a preferred embodiment, the relative aperture selected for each situation is read into the exposure computer (22) by means of a coder placed in the camera control device (21). The corresponding exposure time is calculated by the exposure computer (22) on the basis of the aperture and other exposure parameters and set automatically at the shutter. The exposure parameter reproducing the brightness of a subject to be photographed can be read into the exposure computer (22) either manually or, by connecting a photoelectric brightness sensor (23), automatically. A flash unit (24) can be connected to the exposure computer (22), the flash output of the flash unit (24) can be controlled by output signals of the exposure computer. As a result of a single test flash the number of flashes that may be necessary is calculated and displayed by means of the exposure computer (22).
