  • Patent number: 5164753
    Abstract: An improved camera, and a method of using it, so that a user of the inventive camera may be photographed, together with other objects to be photographed, in a simultaneous manner, without the need for a time delay. The present invention comprises a camera that includes a front primary lens to focus an image of a primary object to be photographed onto a frame of film having a photosensitive emulsion coating a transparent film base. A rear secondary lens focusses an image of the photographer onto a portion of the same film frame through the transparent film base, such that the image exposes the photosensitive emulsion on the front side of the film. A light shield is provided within the camera body to block light from the front primary lens from exposing the portion of the film frame on which light from the rear secondary lens is focussed.
