Tiffen 4x5.65"Combination 85 and Circular Ultra Polarizing Glass Filter - If a traditional polarizer doesn't give you enough "zip", the Tiffen "Ultra" polarizer gives you a little more. Ultra Polarizers bump up your blue skies a touch more just enough to make that critical difference. Tiffen Linear Ultra Pol and Circular Ultra Pol 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.
The Tiffen 85 series will produce natural colors when shooting with tungsten film outdoors.
What do you do when you must take some photos outdoors and all you have left is tungsten film? Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series of filters will "bring back", i.e. color balance the tones in your images. These yellow filters are used to correct differences in color temperature between the recording medium (film/video) and the light source.
It should be noted that an 85 filter produces slightly cooler results than an 85B (with tungsten film in daylight) whereas an 85B converts tungsten film to daylight. The 85C produces the coolest results - more than either the 85 or 85B. However, it is interesting to remember that an 85C is also useful as a creative warming filter with daylight film in daylight.
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). Whereas the 85 series is used for tungsten film under daylight conditions, use the 80 series of filters when using daylight film under tungsten lighting.
