Cokin A Series 2-Point Diffraction Star Filter

The Cokin A Series 2-Point Diffraction Star Filter is designed for use with a Cokin A Series Filter Holder. When used perpendicular to a point light source such as the sun, a light bulb, or a candle; a combination of fine etched line types within the filter help to create a starburst effect with two primary diffraction spikes that extend from the light source. Those diffraction spikes at first share the same color as the light source, but then appear to become multicolored. This is due to the ability of some of those etched lines to separate light into its component low frequency and high frequency wavelengths, resulting in distinguishable colors ranging from red to blue within those starbursts.
