  • Patent number: 4304471
    Abstract: A photographic camera with guide channels built into the camera in a plane parallel to and just a short distance in front of the focal plane in which the film is located during the exposure. Through a slot in the side wall of the camera, with light sealing means at this slot, a removable and interchangeable mask is placed in the camera and pushed in to a position properly aligned with the picture area of the focal plane. The mask has at least one light transmitting portion through which light from the camera lens may reach the film to make an image thereon when an exposure is made, and one or more opaque portions surrounding a slight transmitting portion of the mask. The opaque portions are shaped to provide a border of non-rectangular shape having an outline or silhouette having symbolism or meaning or conveying some thought appropriate to the circumstances of the picture to be taken with the use of the mask.
