Tiffen Filters 4X5.650 85N1.2 FILTER - 4565085N12
4X5.650 85N1.2 FILTER
The Tiffen 4 x 5.65" 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 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 4 x 5.65" / 101.6 x 143.5mm.
