B+W 37mm MRC Basic Circular Polarizing Filter
About this item
This 37mm MRC Basic Circular Polarizing Filter from B+W reduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. Light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing it to scatter into what appears as haze. A polarizing filter arranges 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. Objects and people behind surfaces such as shop windows and car windshields become visible again, a fascinating image enhancement without the need for image processing in post production.
