hi guys, i have a problem with some color stuff. I have various lighting models e.g. 1500 K Candlelight 2680 K 40 W incandescent lamp 3000 K 200 W incandescent lamp 3200 K Sunrise/sunset 3400 K Tungsten lamp 3400 K 1 hour from dusk/dawn 5000-4500 K Xenon lamp/light arc 5500 K Sunny daylight around noon 5500-5600 K Electronic photo flash 6500-7500 K Overcast sky 9000-12000 K Blue sky now i need the white points for them e.g. i found some here http://www.brucelindbloom.com/index.html?Eqn_ChromAdapt.html and wikipedia says:::: http://en.wikipedia.org/wiki/Color_temperature 5000 K (D50), 5500 K (D55), 6500 K (D65), 7500 K (D75), 9300 K. so now i could check:::: D65 = 0.95047 1.00000 1.08883 and this belongs to 6500 Kelvin but lets say i need the Blue Sky 9.000-12.000 how do i find out the white point? What is the formula? I just cant find it :) thank yo for your help
