6.6 x 6.6" Linear Polarizer Filter 4 with a hard-edged line ofThe Tiffen 6. 6 x 6. 6" Linear 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
