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.
