The Tiffen 81 is a light balancing filter designed to provide a subtle warming effect by slightly decreasing the color temperature of your scene. It lowers the color temperature by approximately 100K, allowing you to achieve a 3200K balance when shooting under 3300K illumination.

Constructed using Tiffen's ColorCore technology, the filter features optical glass mounted in a precision metal ring. Please note that using this filter requires a 0.3-stop increase in exposure for accurate results.
