ABSTRACT:
Disclosed herein is a photographic camera having an integral flash unit which illuminates object space through the camera's viewfinder. According to a preferred embodiment, light from an energized flashlamp mounted within the camera interior is reflected into object space by means of a mirror which is pivotally mounted in the camera's viewfinder. Prior to shutter release, the mirror is stored in a position to allow normal use of the viewfinder. In response to actuation of the camera's shutter release mechanism, the mirror pivots to a position on the optical path of the viewfinder, whereupon it reflects light emanating from the flashlamp through the front of the viewfinder and into object space.
