The NiSi Cinema 6.6×6.6″ Enhanced Rotating CPL Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. A polarizing filter arranges, and filters, this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.
