The Tiffen 4 x 5.65" 81 Light Balancing Filter helps to decrease the colour temperature by 100K in order to slightly warm the image to match the colour quality of the lighting. By using an 81 filter, you will be able to achieve a balance of 3200K when the predominant light source is 3300K. The warming effect of this filter requires an exposure increase of 0.3 stops 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 polishing it flat to a tolerance of 1/10,000th of an inch. It measures 4 x 5.65" / 101.6 x 143.5 mm.
