The Haida V-Pro Series 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 a haze. A polarizing filter arranges and filters much of this light, resulting in a noticeable reduction of glare and reflections from non-metallic surfaces (such as water) and an increase in the saturation of skies and foliage.
