This 3 x 3" Combination 85 Amber & ND Filter combines an 85 with a 1-stop neutral density filter. Using tungsten film in daylight will produce a bluish cast in the photograph. The 85 series will produce natural colors when shooting with tungsten film outdoors. An 85 filter will decrease the color temperature from 5500K to 3400K.
Lee resin filters are made from lightweight, optical polymeric materials.
