Tiffen Filters 6X6 85C Color Conversion Filter - 6685C

The Tiffen 6 x 6" 85C Color Conversion Filter helps to decrease the color temperature from 5500 to 3800K, allowing the use of tungsten-balanced film in daylight conditions. The warming effect of this filter requires a 0.3-stop increase in exposure for normal results.

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. It measures 6 x 6" / 152.4 x 152.4mm.
