A Mechanism for Automatically Controlling the Exposure of a Multiprogrammed Automatic Camera,
Abstract
It is shown that the multiprogrammed cameras provides manual diaphragm control by means of a disc and lever with second lever and sprung third lever, and the disc turns with scale relative to the index, to the automatic setting, and to any required diaphragm setting. The circuit of the indicator is broken and its pointer seeks zero, but rests on the lever in a set position for one particular shutter position as set in one of the programmes. One of the releases is now actuated so that the shutter rings turn the rack until it is stopped by the pointer and the shutter timing has been worked off completely. (Author)
