The Cokin Star 8 creates 8 rays of light streaking outward from a central point light source In the image. This can make lighting within the scene take on a more glittering, glamorous appearance. This effect is produced by a series of thin lines etched into the flat optical surface of a clear filter. The size and brightness of the Star lines produced are first a function of the size, shape, and brightness of the light source. A pattern of Crossing lines etched in the filter creates an 8-pointed Star, just a streak through the center of the light. Cokin offers 2, 4, and 8 point Star effects. This filter fits the Cokin M series holder.
