The Tiffen 4 x 5.65″ Coral 1/4 Warming Glass Filter is a  general purpose warming filter which comes in increasing amounts of color temperature correction as the number in the series increases. It is commonly used to produce slightly “orangey” skies and is very popular with cinematographers. From light to heavy, any effect from basic correction to warmer or cooler than “normal” is possible. Corals can also compensate for the overly cool blue effect of outdoor shade (such as shooting against the side of a barn in shade).
