Tiffen 4.5" Round Water White Ultra Circular Polarizer Filter

Tiffen 4.5" Round Water White Ultra Circular Polarizer Filter offer the best polarization effects available for professional motion picture and television work. They extract the maximum of unwanted glare from the scene and render crisp white clouds against a dramatically dark blue sky, like never before.

Ultra Pols get the most from any scene that calls for a polarizer. Some camera-related optics, like a video tap, employ a partially silvered mirror, or beamsplitter. This may require the use of a Circular Ultra Pol, which places a clear, quarter-wave retarder on the camera side of the filter, effectively de-polarizing the light being recorded, after the image enhancement is done. Circular Ultra Pol filters are suitable for virtually all situations; Linear Ultra Pol filters excel in traditional applications.

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.

Water White glass is characterized by a high transmission quality. Typically, it will transmit 98-99% of the light. It also features an anti-glare and anti-reflective quality that makes it useful in a wide range of uses including the movie theater industry, store and art displays. The glass is virtually defect-free and is becoming more and more prevalent in digital equipment.
