Tiffen 85B Color Conversion Filter helps to decrease the color temperature from 5500 to 3200K, allowing the use of tungsten-balanced film in daylight conditions. The warming effect of this filter requires a 0.6-stop increase in exposure for normal results.

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