Dear all,
What is the difference between media white point and the illuminant inside
an ICC profile? I know the Relative colorimetric intent is media-relative;
its values are adjusted to the media white. Does this mean the measured XYZ
values are normalized by the measurement of the device white, or the XYZ
values are normalized by the illuminant (i.e. D50 XYZ values)?
==This is what I assume is correct ==
For relative colorimetric, XYZ values are normalized by the media white. The
media white is the measured XYZ values of the device white (i.e. the XYZ
values of paper illuminated by D50, or of a white patch displayed in the
monitor). Also, I learned that absolute colorimetric values are the relative
colorimetric values adapted to the profile illuminant which in most cases is
D50.
Is all this correct?
Thanks for your help (again),
Hector
