The Tiffen 6.6 x 6.6" 85B/0.6 ND Combination Filter blends both an amber color conversion 85B and a 0.6 neutral density filter. The ND filtration provides a 2 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 6.6 x 6.6" / 167.6 x 167.6mm.
- Combination of both an amber color conversion 85B and a neutral density filter.
- 0.6 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.
