Tiffen 77mm 80B Color Conversion Filter


Enabling the use of daylight-balanced film under tungsten-lit conditions, this 77mm 80B Color Conversion Filter from Tiffen is a cooling filter used to increase the color temperature from 3400K to 5500K. The blue color of the filter has a filter factor of 3x, requiring an additional 1.6 stops of exposure to achieve normal results. The filter is constructed using Tiffen's ColorCore technology, which involves lamenting the filter material between two pieces of optical glass, grounding flat to a tolerance of 1/10,000th of an inch, and mounting within an aluminum alloy ring.
