Blending two distinct filter effects into one, the Tiffen 4x4 Warm Ultra Circular Polarizer Filterfrom Tiffen 4x4 Warm Ultra Circular Polarizer Filterhelps 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.
