Tiffen 4480A - 4X4 80A Filter

The Tiffen 4 x 4" 80A Color Conversion Filter helps to increase the color temperature from 3200 to 5500K, allowing the use of daylight-balanced film in tungsten-lit conditions. The cooling effect of this filter requires a 2-stop increase in exposure for normal results.

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


Features:

- Color conversion filter increases color temperature and provides a cooling effect.
- Converts 3200 to 5500K for using daylight-balanced film in tungsten-lit conditions.
