The Tiffen 6.6 x 6.6" 81A light balancing filter reduces colour temperature by 200K to slightly warm the image to match the colour quality of the lighting. When using an 81A filter, you can achieve a 3200K balance when the dominant light source is 3400K. The warming effect of this filter requires a 0.3 stop increase in exposure for normal results.

This filter is manufactured 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 167.6 mm.


- The light balancing filter reduces colour temperature and provides a warming effect.
- Subtracts 200K to achieve a 3200K colour balance from 3400K lighting.
- The 1.3 filter factor requires a 0.3 stop increase in exposure.
