The Tiffen 4 x 4" 85 Color Conversion Filter helps to decrease the color temperature from 5500 to 3400K, allowing the use of tungsten-balanced film in daylight conditions. The warming effect of this filter requires a 0.6-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 4 x 4" / 101.6 x 101.6mm.
