Dear Ian,
Yes, the i1pro interface is much faster than the DTP94 interface. But I
found some subtle difference between profiles obtained via the two
instruments. Same Eizo CG21 monitor, same basICColor Display v3, same DDC
controls but with two different instruments. The difference? Apart from the
gradation, I don't end up with the same white point 'sensation', even though
I calibrate each time to D50 chromaticities. The problem becomes even more
complex when I try to calibrate through MonacoOptix XR pro software because
I get yet a third kind of interpretation of what a calibrated "D50" should
look like. Its as though basICColor Display and Optix XR each get different
responses from the same instrument, or, interpret differently the same
response from the same instrument. I don't know but it makes me loose my
latin. Imatch v3 gives me yet a fourth interpretation of what D50 is.
Still, at times, I believe X-Rite 'interpretation' of what D50 looks like,
through the DTP94, is more 'correct' than what my EyeOnePro is leading me to
believe. That's why I'm looking for some externally dependable
monitor-friendly D50 chromaticities reference. My CS-100 is factory
calibrated for illuminant A but it has a 'user' calibration mode I am going
to try to have set on some such monitor-firendly D50 chromaticy reference. I
just can't afford a spectroradiometer now :(
