This 77mm B&H Photo Special 50th Anniversary Edition HTC/CP Hi-Transmission MRC-Nano Master Circular Polarizer Filter from B+W helps reduce reflections and glare by filtering out light that has become polarized due to reflection from nonmetallic surfaces. Ambient light from the sun naturally becomes partially polarized because it reflects off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges this light perpendicularly to the reflected light, resulting in a noticeable reduction of glare and reflections from nonmetallic surfaces and an increase in the saturation of skies and foliage.
