Lets pull out a $20K spectroradiometer and test both the instrument
(s) and
the process OK? Otherwise, this is a waste of time.
Andrew,
That noted color guy and author Roy Berns at the Munsell Color Lab
used the same technique to evaluate the LCD ICC profile prediction
errors of ProfileMaker 5 software just 2 years ago. He used it to
look at both 99 patch and 4096 patch targets. He use an Eye-One Pro
for the entire project. Are you implying that his research was
silly, a waste of time, or that he needed a color management consult
before he did this research?
While using the same device without traceable certification to NIST
standards may not give definitive answers on accuracy, it's certainly
not silly or a waste of time. Berns had a Photo Research PR-650
spectroradiometer available that he used for other research problems
in the same publication, but he did not feel it necessary to document
the accuracy of the Eye-One Pro that he used to evaluate the LCD
profile generation component of ProfileMaker.
Are you implying that his research is fundamentally flawed or silly,
or a waste of time?
