The Tiffen 3 x 4" Combination 85/ND 1.2 Filter blends both an amber color conversion 85 and a 1.2 neutral density filter. The ND filtration provides a 4-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85 filtration covers the entire filter plane and converts the color temperature to 3400K for use with type A (tungsten) films.
This filter is constructed from Water White glass and is made using ColorCore technology, a process that involves laminating the filter substrate between two pieces of optical glass, and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 3 x 4" / 76.2 x 101.6mm.
Combination of both an amber color conversion 85 and a neutral density filter.
1.2 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
85 filter converts the color temperature to 3400K, allowing you to use type A tungsten-balanced film in daylight situations.
Water White optical glass for excellent clarity.
