Andrew,
What reference are you judging under the GTI booth to decide which
custom whitepoint matches te the reference ?
If its a paper based reference:
What is the M0 L*a*b* white point of the paper ?
What is a typical luminance of the monitor ?
Do you simulate absolute colorimetric the paperwhite during comparing
the reference and the custom whitepoint ?
I have seen people, which do not want to active paperwhite simulation
during image editing but compare the diplay with a proof. if the proof
is slightly bluish e.g. b* -2 th customa whitepoint needs to higher
The lower the luminance the more yellowish seems a 5000k whitepoint
(also depending from the ambient lightning)
for normal daaylight bureau, I I personally prefer 140 - 160 Candela
insteas of 80-120 Candela referenced ins some specs.
Best regards
Jan-Peter
