Light rays which are reflected by any surface become polarized. Polarizing filters are used to select which light rays enter your camera lens. The Digital HGX Circular Polarizing filter allows you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. It also will enable colors to become more saturated and appear clearer, with better contrast. This effect is often used to increase the contrast and saturation in blue skies and white clouds. PROMASTER Polarizing filters does not affect the overall color balance of a shot.
PROMASTER Digital HGX filters are the highest quality most advanced optical filters available today for digital photography.
