The Kodak 3 x 3" 81EF Wratten 2 Filter is a color conversion filter that helps to slightly decrease color temperatures and provide a warming effect. The 81EF filter adds more warmth to the image for use with tungsten films in natural lighting. It provides a decrease of 650K, helping to render the scene more similarly to incandescent illumination.
This filter measures 3 x 3" / 76.2 x 76.2mm and has a 1.5x filter factor, requiring an increase of 0.6 stop for normal exposure. Wratten 2 filters are constructed from gelatin for ease of use and consistent performance. When compared to the original Wratten filters, Wratten 2 filters are more rigid and durable, easier to handle, and less sensitive to humidity, static cling, and fingerprints.
