Abstract
Abstract A camera including a device for mounting a transparency therein for movement from an operative position in intimate contact with the film to be exposed and an inoperative position clear of the film. A photographic method or system including double exposing the film with the first exposure being made with a transparency in intimate contact with the film by backlighting the object to be photographed to silhouette the object on the film and to expose the transparency onto the film except for the area silhouetted and then removing the transparency and moving a substantially nonreflecting backdrop into position behind the object and frontlighting the object for the second exposure. Where larger backgrounds are required, a reflecting mask having an opening through which the object to be photographed is viewed, is used and during the first exposure the object is backlit and light is reflected from the mask into the camera to expose the film through substantially all of the area covered by the transparency with the exception of the area silhouetted by the object to be photographed.
