The Tiffen 4 x 5" #11 Yellow-Green Filter is a basic contrast filter, primarily for use with black and white film. This yellow-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.
