This is my favorite topic -- among plenty of other favorites topics in color
management... It's one thing that a system arrives at a desired numerical
accuracy, it's quite another that this accuracy also translates into visual
satisfaction. I'm using the term 'satisfaction' here because this term, to
me, is more inclusive than the word 'matching'. Usually I would write
'visual matching', since this is the goal we're after. But the term
'matching' is quite open in the multiple meanings it evokes to many people
-- I've seen things I was told 'matched' when, to my eyes, there was a whole
ocean in between. So, I am trying to qualify the use of the term. And by
using 'satisfaction', I want to acknowledge that many users are not
necessarily after the same Holy Grail I do. This said, the things that
affect the 'match' or that will determine the 'satisfaction' of the observer
include, well, the observer him or herself -- of course --, but also the
light, the light used to illuminate whatever is used to compare against the
screen. There is also the characteristics of the substrate, in the case of a
hardcopy proof, its colorants or pigments (Epson vs HP), the rendering
intent used to convert the 'monitor' colors, the nature of the surround, and
so on and so on, there are just too many of these 'factors' which mediate
our actual visual experience to ignore them when discussing performance
(magenta cast, etc..). So, what's a good monitor calibrating/profiling
package to do for the user? Well, at the very least, get the right numbers
under control, white point, gamma, gray balance. But once the numbers *are*
under some control then, in my view, the better monitor/profiling packages
will allow some "editorial" space for the user to manoeuver over and beyond
whatever level of accuracy was obtained, through the software and the
instrument. Few packages allow this "post-calibration" functionality. I
think only ColorEyesDisplayPro and basICColor Display allow this
capabilities? Oh! Eizo's ColorNavigator also offers this functionality but
only on Eizo's monitors.
There are many schools of thoughts here. I like comparing a ColorChecker to
my calibrated screens whenever I can, to give me confidence in the system.
If I am 'satisfied' with the 'match' then I can come to trust the screen.
Otherwise, I have to scratch my head and find ways to obtain the kind of
match I want. It's not always possible but it's quite often possible.
My two cents / Roger

Hello List Members,
I have a bit of a conundrum and I'm hoping someone can offer up a solution .
. .
I've just purchased the stunning NEC LCD 3090W-BK-SV and it's really
awesome. However, since I had used a 30" Cinema Display and a 23" display
prior to the purchase, I now have a huge color difference between the NEC
30" and the secondary 23" Cinema Display. I don't plan on using the second
display for final color because it's obviously inferior to the NEC. However,
when I try to calibrate the 23" it's way, way, way too magenta and I cannot
get it to shift upon several attempts to profile. I was wondering what (if
any) software might be out there to manually adjust the profile towards a
greener version.
I'm using 2 different spectrophotometers - the NEC Spectraview "eye one" for
the NEC and the old school Eye One for the 23" inch.
The shift is so different it's hard to have them sitting next to each other
and I often use a second monitor when working in Lightroom so I don't want
them to be that markedly different.
Any help would be greatly appreciated.
Thank you,
Kerry
