Cokin 82mm Wide Angle Circular Polarizer Digital Pack (Silver Ring) - Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colors providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter.
The filter factor varies according to how the filter is rotated and its orientation to the sun.
A polarizer should be considered a mainstay for anyone who takes their photography seriously. Along with a UV (Ultraviolet) filter, these filters can make the difference between a successful photo and a snapshot. This filter is really the only way to make a blue sky "bluer". It will also help minimize reflections when shooting into glass (i.e.museum and gallery displays, store windows, etc).
Cokin makes a a wide variety of filters to achieve just about any effect you can imagine. This kind of "filter system" offers photographers a cost-effective way to build a collection of standardized filters for any size lens. The Cokin system is available in various size formats to meet any photo or video need.
Note: Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems and video cameras without problems).
This filter eliminates ultraviolet rays to remove haze from outdoor shots as well as polarizing the light to remove reflections, and increase color saturation, without affecting the overall color balance
