Tiffen 77mm 81B Light Balancing Filter

The Tiffen 77mm 81B Light Balancing Filter helps to decrease the color temperature by 300K in order to warm the image slightly in order to match the color quality of illumination. When using an 81B filter, you will be able to attain 3200K balance when the prevailing light source is 3500K. The warming effect of this filter requires a 0.3-stop increase in exposure for normal results.
