how did you finally set the settings (color space, brightness, contrast, others) to achieve the goal?
Your calibration software "should" enable you to set target values but I would leave contrast alone at the monitor's native value.
You don't normally set the "color space" because the calibration process creates one for your monitor, i.e. a profile.
My calibration software (Eye One Match 3) recommends, for an LCD monitor, 6500k for colour temperature and 120cd/m2 luminance, (= white point or brightness setting).

I my software setting "white balance" screen I adjusted color gain, brightness and contrast, as well as "offset" a little. Until all the values: color temp. and luminance were within specs suggested by software. BTW I used gamma 2.2. Did I do something wrong?

That is correct for Windows.

Does you software report, at the end of calibration, what it has achieved? Eg. Colour Temperature, gamma, min and max luminance? If it does and all looks good, then it's done  Wink
See reply #3 attachment on this thread for a typical result.

It is close enough, but here are gamut for my monitor and printer in comparison to ProPhoto color space.
Does it look good?

It's as one would expect: the printer has a much smaller colour gamut than a good monitor. And, it makes a comment on the use of the ProPhoto Colour space, which is very much larger than any output device  Shocked
What you need to do is make some prints and check that what you see on the monitor matches (more or less) is the same as the print. However, the printer profile comes into the equation then.
I see you have one of Ilford's own profiles there; I never liked the results with those so had custom profiles made.

It Is custom profile for Ilford Smooth Pearl paper.
My printer output is very good comparing to what I see on the monitor.
How does monitor gamut look to you?

It's hard to tell from the diagram; a comparison with Adobe RGB would be more realistic as good monitors now have a gamut close to that colour space. Really good ones (= very expensive) exeed Adobe RGB but would not come near ProPhoto.
I've attached a comparison for my Eizo (95% of Adobe RGB)
It's shows the projection of the gamuts, easier to compare  Smiley
Red = ProPhoto
Blue = Adobe RGB
Green = Monitor
Magenta = Epson R800 with Ilford Smooth Gloss
EDIT: I showed some other gamut comparisons here on this thread:

No worries then  Grin

Looks good.

Looks like it's broken. It happened once before, try later. It's a French Canadian site.

No, there is a Windows version, I have 1.9. Google it and you may find an earlier version somewhere.

It still is although the main site is ok.
If you want to play with comparing profiles, try http://www.iccview.de/content/view/3/7/lang,en/
You can upload a profile and compare, not only visually but quantitatively too.
To check a a calibration result and compare results, some calibration software, like Eye One Match 3, has a validation feature which checks the "dE2000" errors and tells you how much, in Lab terms, how much out of gamut the monitor is compared to the colour patches the calibration uses. I think I've got that more-or-less right  Wink
Attached is a graphical plot of what I get. An average value of <2 is good.

Terry,
Would it be possible for you to send me Perfx Gamut to my email? If so I'll provide it.

Yes, sure.
Send me a message via the forum with your e-mail address and I'll then send it to you from my e-mail account. It's 1.7MB.
Don't put your address on a forum post or the spammers will get it  Shocked

okay, I upgraded to win7 ultimate and everything seems to work.
I also updated NVIDIA driver.
Should recalibrate monitor now?
What, if my white luminance is less than 120 (117) and black luminance is .30? How these numbers affect profile?
Thank you!

also, how do you go about calibrating your monitor and printer based on the same so you get the results when printing?
Probably a good idea but you need to follow Mike's instructions for W7 to utilise the profile, new one or not.

117 is close enough to 120 I would think; 0.3 is the figure you had before I think and you cannot do much about it. As I said, I would have expected a figure a little lower but I have no feel for the practical difference between 0.3 and say 0.1. The luminance values don't have any great effect on the profile as far as I know, just the appearance of the screen with respect to brightness and contrast. If your prints are coming out ok. relative to the monitor rendition, don't worry about it.
