Catalogs like the B+W filter catalog (page 5) lists color temps of various sources. A color meter, I believe from personal experience, is useless outside under simple sunlight source lighting. Now, if you were mixing strobe with sunlight and using white or gold or silver reflectors, a color temp meter might be useful to tell you how to keep everything close to the same temp. But I suspect you are not doing catalog work at hi altitude. Even if you are, the KR3 and KR6 work wonders to convert the hi altitude color temp down to normal. That's basically what they are. Color conversion filters. I also use them on cold gloomy days here along the CA Pacific coast. I think folks in Portland have KR3's welded to their lenses... ;) Jim - -- To unsubscribe, see http://mejac.palo-alto.ca.us/leica-users/unsub.html
