Hello all,
yesterday I had an idea, maybe it's dumb, but I would really like to
hear your opinions. ;-)
Many instruments especially spectrometers seem to have accuracy problems
when measuring at low light levels. Couldn't it be beneficial, if we
would first measure a display at its maximum brightness setting,
subsequently set the brightness to the desired level, remeasure at least
the new white point spectrum (I suppose the white point of the backlight
unit will change when dimmed) and then try to compensate/recalculate the
first measured data based on the new WP/brightness?
Could this strategy be beneficial at least for measuring the very low
gray/brightness levels?
I ask this not only out of curiosity, because I still have a problem to
get a neutral gray axis without visible color shifts (and banding) in
the darker tones with my ColorMunki and a NEC PA241W.
Best regards,
Juergen
