I've been having a hard time fighting with calibrating/profiling
Apple Colorsync monitors, mostly out of confusion about what state to
put the monitor in before calibrating. I think this topic has come up
before, but I wanted to hear if others have a typical procedure for
handling it.
Method 1: Disabling the extension that handles Apples calibration--I
believe it's called something like "Applevision." This takes the
monitor controls back to the original built-in controls without
having the MacOS interfere. Then I calibrate & profile. Usually the
hardware control will allow temperature adjustment, but not RGB
control. Then I run Photocal or whatever to do the job.
Method 2: I've also tried using the Applevision calibration to get
the display at 6500 with no gamma correction, then use Photocal to do
a calibration/profile on top of that.
Method 2 seems to work better despite my best judgement, and the only
reason I can think of for this is that the LUT is not being cleared
when attempting to use method 1. My next thought is to use method 1
but to run something like Colorblind just to clear out the LUT.
It also doesn't help that these are older monitors I've been dealing
with that should really be replaced, but still it would be nice to
have a definite procedure in place for dealing with these beasts.
Funny how Apple's trying to help with the calibration is actually
making the job more difficult.
