Tiffen Filters 5.65X5.65 WTR/WHT 85N3 FILTER - W56585N3

The Tiffen 5.65 x 5.65" Combination 85/ND 0.3 Filter blends both an amber color conversion 85 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 85 filtration covers the entire filter plane and converts the color temperature to 3400K for use with type A (tungsten) films.

This filter is constructed from Water White glass and 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 5.65 x 5.65" / 143.5 x 143.5mm.
