The MovieMate Magnetic Circular Neutral Night Light Pollution Filter from Kase is a neutral night light pollution filter made to fit the MovieMate Magnetic Matte Box. It removes the yellow cast caused by light pollution during night photography, isolating the harmful effect of artificial lights on imaging. Especially useful for late-night, long-exposure imaging near cities or other sources of light pollution, this filter cuts light from the color spectrum, like that from low-CRI light sources.
