- 1Description
The Singh-Ray 84 x 120mm 81A Light Balancing Filter helps to decrease the color temperature by 200K in order to warm the image slightly in order to match the color quality of illumination. When using an 81A filter, you will be able to attain 3200K balance when the prevailing light source is 3400K. The warming effect of this filter requires a 0.3-stop increase in exposure for normal results.
Singh-Ray rectangular filters are constructed from high-quality CR-39 optical resin for notable image quality and clarity. This filter measures 3.3 x 4.7" / 84 x 120mm and is compatible with Cokin P filter holders.

- Subtracts 200K in order to attain 3200K color balance from 3400K illumination.
