It has a tubular enclosure open at both ends and is carrying at one end a fastener for releasably fastening the enclosure to an objective. Adjacent its other end the enclosure has a means for supporting a special color filter. Between the color filter and the objective is an illuminating structure for illuminating the color filter so as to achieve the dominant color effect.
