TIFFEN W6666UPOL 6.6X6.6 WW ULTRA POL LINEAR (Used)

Polarizers provide colour and contrast enhancement. Reflected light often shows up as whitish glare that washes out colour in an image. A Polarizer corrects this problem producing deep, dramatically blue skies. It also removes glare from non-metallic surfaces, such as windows and water. Colour saturation in general, especially outdoors, can be improved significantly. A Circular Polarizer has the same effect as a Polarizer and is used on cameras with beam splitting metering systems commonly found on auto focus SLR's (for most 35mm auto-focus cameras see your camera manual).

UltraPol – yet another tiffen advance, helping cinematographers and videographers realize their creative vision. Tiffen Linear UltraPol and Circular UltraPol filters 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. Distracting reflections from water and windows become invisible with the magic of the UltraPol filter. UltraPols 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 UltraPol, 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 UltraPol filters are suitable for virtually all situations; Linear UltraPol filters excel in traditional applications. Rotating the UltraPol varies the effect to meet your needs. They are available in a wide array of sizes and require 1-2/3 stop exposure compensation. Tiffen precision-crafted filters are the overwhelming choice of film and video professionals around the world. Their superior quality is backed by the Tiffen ten-year warranty.
