  • Patent number: 5835795
    Abstract: A portion of a frame of film is pre-exposed to a first image by subjecting the film to a low intensity exposure while masking a portion of the film. The film is then used in a conventional camera along with a non-opaque exposure limiting device. The non-opaque exposure limiting device is positioned between the camera lens and the film. During exposure of the film to a second or target image, the first image is partially re-exposed thereby enhancing the stability of the picture while capturing the target image on the unexposed portion of the frame of film. The two images are then developed in a conventional manner to produce a relatively smoothly blended composite photograph.
