In my view yes. > By the way - the whole "just scaling" they do - is it even correct > /under/ "adapted to illuminant" assumption ? I don't know where the "just scaling" thing comes from in the first place. It doesn't appear to have a Color Science foundation (I'd be more than happy if someone can point me to some justification in the color science literature). One could make a case that it's some sort of special case of chromatic adaptation, where the established research results don't apply, but I think the onus is on such a claim to show why this is so. [ My suspicion would be that it is based on a print shop "rule of thumb" or shortcut. It's certainly more normal to do similar maths when specifying "media included" or "media excluded" densities or XYZ values. ] Graeme Gill. ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
