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.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass and grinding flat to a tolerance of 10,000th of an inch. This filter measures 2 x 2" / 51 x 51mm.
