The Tiffen 4 x 5.65" 81EF light balancing filter helps decrease the colour temperature by 650K to slightly warm the image to match the colour quality of the lighting. By using an 81EF filter, you will be able to achieve a 3200K balance when the dominant light source is 3850K. This filter's warming effect requires a 0.6 f-stop increase in exposure for normal results.

This filter is manufactured using ColorCore technology, a process that laminates the filter substrate between 2 pieces of optical glass and polishes it to a tolerance of 1/10,000th of an inch. It measures 4 x 5.65" / 101.6 x 143.5 mm.
