Promaster 4552 40.5mm Circular Polarizing Filter Field & Voice Recorders With this battery packFeatures: Light rays which are reflected by any surface become polarized and PROMASTER Polarizing filters are used to select which light rays enter your camera lens. They allow you to remove unwanted reflections from non metallic surfaces such as water, glass etc. They also 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.
