Because I am not impressed with the kind of calibration I am getting from my
Eizo ColorEdge CG21, after throwing what I believe are the best monitor
calibration software and hardware at it, over the last month. I figured, if
all else fails, like I had the impression up until yesterday afternoon, when
I posted my message on the List, I might as well try a manual solution to
the problem.
Over the years, like so many people on this list and elsewhere, I am sure, I
have developped a mental image of what believable grays ought to look like
on a monitor. And I don't have to stress, here, the importance of grays on a
monitor.
I'd be curious to see what OptiCal and a Spyder would do to my Eizo's grays.
I'd be curious to see what an EyeOneDisplay with ColorNavigator or with
iMatch or with basICColor Display would do to my Eizo's grays. But I don't
own neither of these instruments.
So, quite frankly, I was getting fed up. Add to that the fact that I've been
trying to reach Eizo's tech support for the last three weeks without any
success.
Finally, late last night, instead of watching the basketball game on
television, I tried iMatch with my EyeOnePro. Hmmh. The results were better.
Slightly better grays. But, then, just for the heck of it, before I threw
the towel once and for all and conclude that only a manual solution to the
problem would bring me peace of mind, I launched Fuji ColourKit Monitor
Profiler v4.04, and, with the help of my EyeOnePro, a smalll miracle
happened : I finally got good grays! The kinds of grays I've gotten
accustomed to from all those years of staring at CRTs. Maybe not as good as
an Artisan? I don't have one to compare but it is nevetheless very good for
me.
So much so that, for all intents and purposes, I am happy camper today with
my Eizo, and I'll burry, for now, the idea of writing my own video
calibration routine. In the coming days and weeks, I will dig out my Excel
spreadsheet, take out measurements of the Macbeth, in Lab, as displayed in
Photoshop's RelCol mode to the screen, and quantify the quality of Fuji's
science on my Eizo.
Thank's for you reply and help, Steve,
