The Tiffen 3 x 3" 80D Color Conversion Filter helps to increase the color temperature from 4200 to 5500K, allowing the use of daylight-balanced film in tungsten-lit conditions. The cooling 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 3 x 3" / 76.2 x 76.2mm.
