Thank's. We tried to sweat the details as best we could.

Good idea.

The LaCIE software does not provide any post-calibration editing facility at
all?

Or aim for lower than 5000K, like 4700K. But you got the idea of cheating on
the target CCT to get what you know you want out of the sotware. I'm in the
same boat here, you know, with basICcolor Display or ColorEyes Display
since these excellent calibration and profiling packages (my preferred at
the moment) are at the mercy of whathever instrument is used for performing
the actual measurements. So, if the EyeOnePro is slightly off then all bets
are off.

Yes, that's an idea.

Maybe because iMatch cannot directly access the internals of your LaCIE? And
therefore relies on setting the desired color temperature and gamma through
your computer LUTs, which, as many indicated here in the past, looses
discrete levels on your screen?
> Does anyone out there have any suggestions or experience with this?
You can always experiment with "pre-setting" your choice of color
temperature manually on your LaCIE and instruct iMatch to use the "native
white point" CCT. But that's no guarantee that you wouldn't already have
ended up with banding just manullaly presetting the white point to 5000K but
it's worth trying. As you know, there is the ongoing argument on this List
that many of the better LCD monitors, like the ACD (but not the Eizo CG
series or the NEC more expensive LCDs), are "factory calibrated" at certain
color temperatures such as 6500K or so, and as a consequence any tampering
of this optimized state of affairs upsets the quality of their performance.
While this is undoubtely possible, what do you do if, like many others,
would rather use 5000K for your calibration? Short of coming up with your
own manual calibration (making all the tradeoffs yourself, visually or
numerically, step by step, with some custom designed software), I don't know
how else you can get over the calibration of your LaCIE without the
assistance of some software?
