More Information
Summary:Photographic apparatus, preferably a camera, having a reflex optical system for exposing film units which include a transparent outer sheet or layer through which image-bearing light is transmitted to expose photosensitive materials within the film unit. A reflex mirror, forming part of the optical system, is arranged at an optimized position with respect to the camera exposure plane to prevent light rays reflected from the transparent outer sheet from impinging the mirror at an angle of incidence which would redirect the light rays back to the film unit thereby causing a second exposure or "ghost image".
