Enabling the use of daylight-balanced film under tungsten-lit conditions, this 138mm 80C Color Conversion Filter from Tiffen is a cooling filter used to increase the color temperature from 3800K to 5500K. The blue color of the filter has a filter factor of 2x, requiring an additional 1 stop 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.
Blue color conversion filter increases color temperature and provides a cooling effect.
Converts 3800K to 5500K for using daylight-balanced film under tungsten lighting.
Filter factor of 2 requires approximately 1 stop of additional exposure to maintain normal results.
ColorCore technology, which permanently laminates the filter material between two pieces of optical glass, maintains image clarity, accuracy, and consistency.
Aluminum filter ring is both lightweight and durable.
