The Tiffen 4 x 5" #13 (2) Green Filter is a basic contrast filter, primarily for use with black and white film. This green filter subtly darkens skies and lightens foliage. It is commonly associated for use with portraiture and attaining greater separation from skin tones and outdoor backgrounds. When compared to the #11 yellow-green filter, the #13 helps to lighten foliage and other green-colored subjects more.
