Is it just me - or does anybody else think that the Eye One Pro is a

A Spectrophotometer isn't ideal for display calibration in handling
dark
measurements but much better than a colorimeter with filters
assuming an
sRGB behavior on a wider gamut device.
So I wasn't imaging the problems then - the Eye One Pro isn't good for
shadows :-(
Cheaper devices do a much better job - DTP94 is (was) my particular
favourite.
In the cases you site, yes, it will be superior. But if you use it
on a wide
gamut display, you'll encounter errors in white point measurements
(I think
Karl Lang calculated a 500K 'error' with a Colorimeter on the 2690
over what
it should be, based on a $20K Spectroradiometer).
Karl would need to convince me that that presents more of a problem
than shadow mush for day to day retouching work on my wide gamut
display.
PS. Who cares if a monitor matches 96% of AdobeRGB anyhow? What kind
of "standard" is AdobeRGB - the *standard* for lazy Photoshop users
who don't know any better? That figure is as useful as the scanner
manufacturers DMAX values...
Like everything else, it has advantages and disadvantages. If you're
working
with imagery that largely falls close to sRGB, its actually going to
be a
disadvantage. If you're working with very saturated imagery, its
useful
since you can now view colors outside sRGB.
As for a standard, who ever said it was a standard?
Well, if it's NOT a standard - why are these manufacturers falling
over themselves to match it?
I'm working with imagery that falls outside of AdobeRGB - as is
anybody who works with decent scanning equipment (or pro digital
cameras). I'd rather the monitor manufactures made an effort to match
the blues that we get from scanned transparency rather than the weird
green of AdobeRGB. Or even made more of an effort to match process
cyan :(
