This 86mm Tiffen 85B ND Filter 86mm 4-Stopblends both an amber color conversion 85B 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 85B filtration covers the entire filter plane and converts the color temperature to 3200K for use with type B (tungsten) film.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

1.2 Optical Density    ColorCore Technology    Amber 85B and Neutral Density    Warming Filter to Decrease Color Temp    ND Filter to Increase Exposure Length

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

1.2 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.
