Abstract: A photographic background device enables a photographer to include a scene reproduced on a film transparency as background for photographed subjects. A transparency is illuminated while a beam splitter mirror directs light from the illuminated transparency to the camera lens, while allowing light from the subject to pass through the mirror to the camera lens. A movable lens system of positive power is provided to allow the transparency image to appear in focus at the lens. Vignetting is alleviated by locating a concave mirror on the side of the beam splitter opposite the side on which the movable lens system is located. In this manner, the illuminated film transparency image will pass through the beam splitter, be reflected by the concave mirror back to the beam splitter and be reflected from the beam splitter to the camera lens.

Abstract: A reflector or diffuser system is provided for an electronic flash unit. The system comprises an inflatable pillow having a front ply and a back ply with a valve carried by the pillow for enabling inflation thereof. A resilient strap is used for securing an electronic flash to the pillow by overlying the electronic flash and urging it tightly against one of the plies. A filter is removably connected between the one ply and the face of the electronic flash.
