  • Overview

    Tiffen - Filters 85 Linear Polarizer  4.5" Round  Self Rotating (SR) can create deep blue skies, provide a general saturation to all colors, reduce glare, and minimize reflections.

    The 85 color conversion aspect of the filter provides a warming effect and decreases the color temperature from 5500K to 3400K, allowing the use of tungsten balanced film in daylight conditions.

    The linear polarizing aspect of the filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A linear polarizer differs from a circular polarizer in that it does not supports use of a camera's autofocus or auto exposure functions; it is best suited for use with manual cameras, such as view cameras, that are not dependent on internal mechanisms to determine focus or metering settings.

    There is a total filter factor of about 6x, requiring an increase of 2.6 stops for normal exposure. Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4.5" / 114.3mm in diameter and is mounted within a metal ring.

    Linear polarizer and 85 amber color conversion filter combination.
    Total filter factor of approximately 6x requires 2.6 stops of additional exposure for normal results.
    Warming 85 color conversion filter decreases color temperature from 5500K to 3400K for using tungsten-balanced film in daylight conditions.
    Polarizer helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.
    Clears up haze in distant landscapes and provides more saturated, vivid colors.
    Strongest polarizing effect when used at a 90° angle from the sun.

    Tiffen Tip: Polarizing filters achieve different effects depending on the photographer's position to the sun. To get maximum darkening of the sky, the photographer stands sideways to the sun (shoulders point to it) with the sun fairly close to the horizon. As he or she turns toward or away from the sun, the darkening is lessened. When the sun is directly overhead, only a small part of the sky near the horizon can be darkened. The Polarizer also removes unwanted reflections in highly reflective surfaces such as on cars or windows.
