ABSTRACT:
A method and a camera for combination pictures in a photograph in which a transparency film is mounted in a viewer in front of the camera for sighting the relative positions of an image to be photographed and an image to be exposed within the camera. The viewer is removed and the image is photographed onto a primary film while at the same time a secondary film, having a dark figure, is located against the primary film to prevent the primary film from being exposed in the area of the dark figure. The dark figure secondary film is removed from adjacent the primary film and another secondary film, having an image corresponding in shape to the dark figure and having a dark background, is positioned against the primary film. The primary film is then exposed a second time, and the image contained on the other secondary film is recorded on the primary film. The images recorded on the primary film are a composite image. Three embodiments of mechanisms for movement and location of the secondary films are disclosed including a wheel, a sliding framework, and a slidable rectangular film sheet.
