Exclusive Tiffen filter Creates brighter, more saturated reds, rust browns and oranges Use with Polarizer for dramatic outdoor effects The Tiffen "ENHANCING Filter" is a combination of rare earth elements in glass. Made of didymium glass, it's ideal for photographs where red, brown and orange subjects should be enriched or appear more intense. Old rustic barns, flowers, fire engines and automobiles, historic brick buildings, earth tone rock formations, strawberries and tomatoes, are some of the many subject possibilities in which a Tiffen enhancing filter can improve the color saturation of your photograph. It completely removes a portion of the spectrum in the orange region. The effect is to increase the color saturation intensity of certain brown, orange, and reddish objects by eliminating the muddy tones and maximizing the crimson and scarlet components. Its most frequent use is for obtaining strongly saturated fall foliage. The effect is minimal on objects of other colors. Skin tones might be overly warm. Even after subsequent color timing or correction to balance out any unwanted bias in these other areas, the effect on reddish objects will still be apparent. The Tiffen ENHANCING filter is also ideal for earth tone rock formations, architecture, woodwork, faded rustic barns and any photos where red, brown and orange subjects should be enriched or appear more intense. For truly spectacular images, try combining the Tiffen enhancing filter with a Tiffen Polarizer. The Tiffen enhancing filter will intensify color in the foreground landscape, while the Tiffen Polarizer will produce beautiful blue skies for maximum color saturation. All warranty is done through the manufacture.
