Tiffen 4.5' Round Warm Ultra Circular Polarizer Filter

Tiffen 4.5 Round Warm Ultra Circular Polarizer Filter

Blending two distinct filter effects into one, the 4.5 Round Warm Ultra Circular Polarizer Filter from Tiffen helps to reduce reflections and glare as well as provide an overall warming tone. The Ultra circular polarizer effect provides deep, saturated, and rich colors and efficiently cuts haze and reflections from non-metallic surfaces. Complementing these effects, the incorporation of a Warming 812 filter into the design adds a natural glow to skin tones and other subjects, making it ideally suited for use in outdoor open shade conditions where there is an excessive blue color cast.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings. It measures 4.5 in diameter and is suitable for use in select matte boxes and sunshades.

Ultra circular polarizer significantly reduces reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface.

Lessens haze in distant landscapes and provides more saturated, vivid colors.

A circular polarizer differs from a linear polarizer in that it supports full use of a camera s autofocus and auto exposure functions.

Strongest effect when used at a 90° from the sun.

Warming 812 filter effect provides an overall warm tone to the image and is ideal for working in conditions with an overwhelming blue color cast.
