        any kind, as for closing the passageway for molten iron

     4. (Photog.) A mechanical device of various forms, attached
        to the aperture of a camera lens for opening and closing
        to expose the plate. It is usually designed so that the
        time during which the aperture is opened may be varied by
        a manual dial or by some automatic mechanism, thereby
        allowing proper exposure of a photographic film under
        different intensities of light.
