Tiffen 72mm 25 Filter (Red)

Product Description The #25 Red Filter from Tiffen is a filter designed to build contrast in black and white photography and creates separation between the tones. Using this filter it creates dramatic skies or simulate a moonlit scene during the day by slightly underexposing the image and also eliminating fog and haze. Infrared film is enhanced with extreme contrast turning skies even more dramatic and turning foliage white in landscape photos. The filter has a filter factor of 8, so you must increase your exposure by 3 stops to compensate. Tiffen filters are not dyed, but are manufactured by using ColorCore technology. This process laminates the filter material between two pieces of optical glass and grinds down and polishes the glass. The glass is then mounted to the metal ring, which after that can be screwed onto the lens for the desired effect. Amazon.com May be used to simulate a moonlit scene at midday with slight underexposure. When used with infrared film, this filter yields extreme contrast in skies, turns foliage white, and cuts through fog and haze.
