I'm a little confused about the -k parameter versus the -y parameter
used with an eye-one pro and dispcal. I think I understand what the k
option do, I'm not so sure about the -y with a spectrometer.
If I create a cal file with no option like "dispcal -m -v normal", I
end up with this line in the cal file for my LCD display.
BLACK_POINT_CORRECTION "1.000000"
If I specify -yl on th command line I end up with
BLACK_POINT_CORRECTION "0.000000"
In the documentation I read about the -k option "Normally dispcal will
attempt to make all colors down the neutral axis (R=G=B) have the same
hue as the chosen white point." This means 1, I guess. But then there
is sentence about 1 for CRT displays and 0 for LCD display, as default
values. So this means this is the default behavior, only if I use
the -y option? I mean there is no way for dispcal to understand by
it's own if I use a lcd or crt monotor, and if that not specified it
use default "1"?
Will the command "dispcal -m -yl monitor" and "dispcal -m -k0
monitor" give the same result? I can see in both cases I end up with
BLACK_POINT_CORRECTION "0.000000". I just wonder if there are other
"black magic" involved when I use the -y option.
