Tiffen's 67mm 6 Yellow 1 Camera Filter is a black and white contrast filter.





Filters for black and white photography perform a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections and more dramatic landscapes.





Although originally intended for use with black and white film, these filters can also be used as a creative tool in color imaging.





This light yellow filter provides partial correction of panchromatic materials to visual luminance values of outdoor scenes.The Tiffen 67mm #13 (2) Green Filter is a basic contrast filter, primarily for use with black and white film. This green filter subtly darkens skies and lightens foliage. It is commonly associated for use with portraiture and attaining greater separation from skin tones and outdoor backgrounds. When compared to the #11 yellow-green filter, the #13 helps to lighten foliage and other green-colored subjects more.





There is a 2x filter factor with this filter, requiring an increase of 1 stop for normal exposure. Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 10,000th of an inch, and then mounting to precision metal rings.The 67mm #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.The Tiffen Cordura Four Filter Pouch is a padded Cordura nylon pouch made to hold four round filters up to 77mm in diameter. There are four mesh pockets to hold the filters.
