The Tiffen 4 x 4″ 85B/0.9 ND Combination Filter blends both an amber color conversion 85B and a 0.9 neutral density filter. The ND filtration provides a 3 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 2 pieces of optical glass, and grinding flat to a tolerance of 1/10,000th of an inch. This filter measures 4 x 4″ / 101.6 x 101.6mm.

Combination of both an amber color conversion 85B and a neutral density filter. 0.9 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.
