This is what people keep saying to beginners like me :-). However, it
seems to me quite easy. Calibration = through translation (matrix or
lut) make the monitor display colours closer to some desired target.
Profiling = measuring the screen to see how it actually does display
colours. One can profile a calibrated display or an uncalibrated
display.
However, a source of confusion may be that I have misunderstood where
the data is. I thought that for an .icc profile from dispcal vgct =
calibration curves and rTRC/gTRC/bTRC = profile (*after* vcgt
applied)... but I'm no longer that sure. I must try to look further into
this, source code if I must. It will be impossible for me to find the
source to my experienced (or imagined) problems if I don't have full
understanding how calibration and profiling is applied.
Anyway, I'm sorry for being clueless, I know it's not fun educating
clueless beginners like me... I'm trying not to say clueless things, but
it seems today like I need to spend some more time on this before
leaving the clueless stage :-).
