Thanks for help. Regards, Andre Sch|tzenhofer
Did you take a look at Bruce Lindbloom spreadsheets?
Otherwise, you could always set up your own spreadsheets to calculate XYZ
tristimulus values from whathever CIE illuminant and Observer you care. It
isn't as hard as you think. Plus, you'll really feel geeky after you've done
it.
If I were you, I'd get hold of Color Technology by Burns. There are some
good worked out examples that will help you get started. Reflective
colorimetry is a cinch compared to emissive colorimetry.
