The Tiffen 138mm Hyper Star Filter is a cross screen filter providing a more natural, less synthetic appearance than a conventional star effect filter. This filter produces approximately 14 reflected light points, stemming from specular highlights, in different shapes and lengths. This effect is caused by thinly etched lines on the surface of the filter. Star effect filters are most effective when not used in combination with other filters. This filter also incorporates a rotating filter mount, which allows you to more finely tune the orientation of the star effects around specular highlights.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.
