ABSTRACT:
An automatic camera of the type having distinct ambient and flash exposure modes of operation is provided with a scene light detecting apparatus which provides an electrical output signal that is utilized to control exposure under both ambient and flash illumination conditions. The scene light detecting apparatus is structured to have a predetermined angle of acceptance and an arrangement which, depending on the exposure mode in which the camera is operated, aims the angle of acceptance in different angular directions at a scene to be photographed. When the camera is held in its normal picture taking attitude, the scene light detecting apparatus is aimed below the camera's horizontal axis to accommodate ambient lighting conditions and is responsive to the insertion of an artificial light source into the camera to aim above the camera's horizontal axis to accommodate flash illumination conditions.
