4 x 4" Ultra Circular Polarizer Filter .6 3 ND Filter is aThe Tiffen 4 x 4" UltraPol Circular Polarizer 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
