The 3 x 3" Tiffen Combination 85B/ND Filter blends both an amber color conversion 85B and a 0.3 neutral density filter. The ND filtration provides a 1-stop exposure reduction for darkening the entire image in order to photograph with a wider aperture or slower shutter speed than normally required. The 85B filtration covers the entire filter plane and converts the color temperature to 3200K for use with type B (tungsten) films.
This filter 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 3" / 76.2 x 76.2mm.
Combination of both an amber color conversion 85B and a neutral density filter.
0.3 ND filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
85B filter converts the color temperature to 3200K, allowing you to use type B tungsten-balanced film in daylight situations.
