DESCRIPTION

The 81 Series of filters control the bluish coloration that affects daylight film. They can also remove excessive blue from the effects of electronic flash. Good for general scenics when the photographer wishes to remove the bluish cast from open shade or just add warmth to the photograph, with an 81EF having the greatest effect. This filter combines an 81EF with a .6 (2 stop) neutral density filter. It is glass and measures 75 x 75mm (3 x 3") x 4mm thick.
