The Heliopan KR 6 (81EF) Filter has double the strength of the KR3 (81A), and leads to neutral color rendition in strong haze or in the mountains above 2500m (8200'). A KR6 filter will allow you to correct white balancing problems when you wish to reduce the color temperature of the shot and bring your tones back to a more acceptable level.
