Enabling the use of daylight-balanced film under tungsten-lit conditions, this 77mm 80D Color Conversion Filter from Formatt-Hitech is a cooling filter used to increase the color temperature from 4200K to 5500K. Since the 80D is not a full conversion filter, it produces a slightly warmer-than-daylight effect compared to stronger 80-series filters, such as the 80A and 80B. The blue color of the filter has a filter factor of 1.5x, requiring an additional 0.6 stops of exposure to achieve normal results.
This filter is constructed from Schott glass to maintain high image clarity and color fidelity, and it features a lightweight yet durable aluminum filter ring with 77mm front threads.
