The Tiffen 6.6 x 6.6" 81D Light Balancing Filter reduces the colour temperature by 500K to slightly warm the image to match the colour quality of lighting. By using an 81D filter, you can achieve a 3200K balance when the dominant light source is 3700K. The warming effect of this filter requires an exposure increase of 0.6 stop to achieve 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 it flat to a tolerance of 1/10,000th of an inch. It measures 6.6 x 6.6" / 167.6 x 167.6mm.


- Light balancing filter that decreases colour temperature and provides a warming effect.
- Subtracts 500K to achieve a 3200K colour balance from 3700K lighting.
- Filter factor of 1.5 requires an exposure increase of 0.6 stop.
