Abstract
The 'f' stop of a camera having a fixed shutter speed is automatically set by a galvanometer type control component that is energized by a mechanically powered electric generator which constitutes an integral part of the camera. The shutter is tripped in predetermined time-delayed sequence relative to tripping of the generator and the latter is automatically recocked along with the shutter when the film is advanced. Precise and reliable dynamic regulation and setting of the 'f ' stop as the picture is being taken is thus achieved without the aid of a battery.
