The Tiffen 4 x 5.65" 80C Colour Conversion Filter allows you to increase the colour temperature from 3800 to 5500K, enabling the use of daylight-balanced film in tungsten lighting conditions. The cooling effect of this filter requires a one-stop exposure increase for normal results.

This filter is manufactured using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding it to a tolerance of 1/10,000th of an inch. It measures 4 x 5.65" / 101.6 x 143.5 mm.
