I am aware of the color temp vs. UV issue, but did not know how others compensate for it. Other than ND filters on the Noct, I don't use filtering of any kind. /Mitch Zeissler - -----Original Message----- From: Jim Brick [mailto:jim@brick.org] Sent: Wednesday, November 14, 2001 12:01 PM To: leica-users@mejac.palo-alto.ca.us; leica-users@mejac.palo-alto.ca.us Subject: [Leica] Re: High altitude question Use a B+W KR3 filter. The higher you go, when there is clear blue sky, the higher the color temp as there is less atmosphere (moisture & stuff that is packed down at lower elevations). I've taken ton's of Leica photographs in the Colorado Rockys and after the first roll, started using a KR3, and all was well after that. Please note, it is NOT UV that is causing the blue, it is simply a higher color temp of the light. Your Leica lens has all of the UV filtering built-in. You need to warm up the light, convert it back down to 5000-8000 Kelvin (from roughly 12,000 Kelvin) color temp. Use a KR3.
