The Cokin P039 (81Z) Filter has been specially designed for portrait imaging. Its warm pink coloring makes the skin look attractive and gives a natural tone.
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.
