The Tiffen 6.6 x 6.6" 80B colour conversion filter increases the colour temperature from 3400 to 5500K, allowing the use of daylight-balanced film in tungsten lighting conditions. The cooling effect of this filter requires an exposure increase of 1.6 stops 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 flat to a tolerance of 1/10,000th of an inch. It measures 6.6 x 6.6" / 167.6 x 167.6mm.
