B+W 77mm Circular Polarizer MRC Filter
Highlights Helps to Eliminate Reflections and Glare Reduces Haze and Blue Cast in Landscapes Greater Color and Tonal Saturation MRC Multi-Resistant Coating Rugged Brass Filter Ring High Quality Schott Glass Features The B+W 77mm Circular Polarizer MRC Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. 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. Read More
