Abstract
Exposure control apparatus for a camera having an objective lens, an unregulated, fixed output flash device which, in the absence of ambient light, provides one-half stop of underexposure of a photographic subject located at the near limit acceptable image focus point of the lens, and a mechanism for automatically controlling an exposure in accordance with the intensity of the ambient light. In a flash exposure mode, the mechanism is operated to produce an exposure which, in the absence of artificial illumination, would provide one-half stop of underexposure of the photographic subject. The total exposure, flash plus ambient, is within .+-. one-half stop of a nominally correct exposure throughout the useable depth of field of the camera lens.
