Tony Do remember when considering the simulation of a lighting effect - that <human adaptive vison> would adjust (although perhaps not entirely) for the white point as seen since the eye greybalances on the viewing light. This is why tungsten light indoors does not look yellow to the eye but it does to daylight film.
Correcting for absolutely the measured colour temp would result in a <daylight transparency like> image. And that's not what the eye would have seen. listsubs-at-arimage.com (Tony Riley)::4/12/04::3:26 pm:: GMT-0000 >there appears to be no easy way of simulating a >particular colour temperature in degrees kelvin? > >As for why I wanted to do this in the first place, I thought it would be >interesting to try and see how some of the paintings in the tombs at the >Valley of The Kings might have looked to the people that painted them.
