Description
The Tiffen 6.6 x 6.6" Combination 85/ND Filter blends both an amber color conversion 85 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 85 filtration covers the entire filter plane and converts the color temperature to 3400K for use with type A (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 6.6 x 6.6" / 167.6 x 167.6mm.
Combination of both an amber color conversion 85 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.
85 filter converts the color temperature to 3400K, allowing you to use type A tungsten-balanced film in daylight situations.
