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.
ProMaster polarizers do not affect the overall color balance of a shot.
It is important that you choose the correct version of ProMaster Polarizer for your camera. Many of today's cameras use semi-silvered mirrors or prisms to split the light entering the viewfinder in order to calculate exposure and focusing distance. Polarizing filters can sometimes interact with these items to give unpredictable exposure or focusing. So we recommend that you choose a circular polarizer unless you have a manual focus camera which has no beam splitter.
If you will be using your Polarizing filter on a lens which has a full frame focal length of 28mm or wider, we recommend that you use a ProMaster Digital HD Filter to avoid a possible vignette effect.

The ProMaster Multi-Coated UV filter absorbs the ultraviolet rays which often make outdoor photographs hazy and indistinct. It is a multipurpose fine-weather filter for color as well as black and white films. Also serves as a permanent lens protector.
The multi-coated filter has the ability to minimize reflection at the filter surfaces which reduces flare and ghosting. The result is an average light transmission of over 97%, giving sharp contrast and well balanced color; thus enhancing the performance of today's multi-coated lenses.
