Tiffen 52mm 21 Filter (Orange) and Tiffen 52mm 25 Filter (Red)

Tiffen 52mm 21 Filter (Orange)The #21 Orange Filter from Tiffen is a filter designed to build contrast in black and white photography and creates separation between the tones. The filter absorbs blue and blue-green colors, rendering blues darker such as for skies in landscape or aerial photos and water in marine shots. The filter has a filter factor of 4.5, so you must increase your exposure by 2 1/3 of a stop 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. Strong contrast in B&W images Ideal for landscape, marine, or aerial photography Absorbs blue and blue-green colors Renders blues darkerTiffen 52mm 25 Filter (Red)Filters for black and white photography perform a variety of filtration effects including contrast control, enhanced skin tones, tonal corrections and more dramatic landscapes.

Use with infrared film to yield extreme contrast with skies, turn foliage white and cut through fog and haze.
