Ideal for portraiture, the 4 x 5" 812 Warming Filter from Tiffen is used to improve skin tones when working in cool lighting conditions. This filter offers a greater warming effect than a skylight 1-A filter, and is well-suited for use outdoors on overcast days or on sunny days when working in open shade. It can also be used to absorb the strong blue cast of an electronic flash for more balanced, lifelike skin tones.

The filter is constructed using Tiffen's ColorCore technology, which involves laminating the filter material between two pieces of optical glass and grounding flat to a tolerance of 1/10,000th of an inch.
