Apple's LCD's are lot closer to D65, Barco reference closer to D50. Not sure about the new Eizo, but the last one I saw was very close to D65 at native white. Same goes for laCie LCD.
Dear Neil, before I leave for some days on location, I would like to ask about these lines above.
Just a few days ago a client who is trying to get into Color management the "cheap" way, asked me if I could use some simple tool to make some basic calibration for his monitors so we can stop arguing about why my files print as I see them in my monitors and why he does not see the same thing.
Case is, I told him we could use the most basic tools as a start up, by invoking Adobe Gamma utility, the Monaco EZ Color2 solution ( just a variation of Adobe Gamma) and /or SuperCal utility (which provides of a little more refined calibration tools), and I thought this would provide at least a ballpark approach to color.
The funny thing came out when I finally had the time to go to his office ,I found he is using 2 computers and 2 monitors, one being a 17 inches LCD ( and iMac 17" Flat Panel actually) and a standard 17" ViewSonic CRT.
I just run the utilities as to provide a basic set up and ended up with 2 altogether different looks for both screens. I just run the tests individually ( different offices), but then the client asks: well, which monitor should I use to see colors if they look soo different?
The only thing I found out, but totally empirically, was that if I run the LCD in 2,2 ( which being a Mac, is supposedly wrong, and it should go at gamma 1,8 .... or is this another Urban Myth?) and setting white point at D65 level I could barely get any closer to the CRT for same settings, but in actual, factual reality, if I arbitrarily set the LCD White Point to D50, (both monitors still set at gamma 2.2), I get the "creamy" look of the CRT set at D65 much more closely, but I understand this can't just be done like this. There must a reason for this that evades me.
I just told the guy that I would return to re-check the monitors, while suggesting he should think on getting more sofisticated calibration gear to make it "the right way", and picking one monitor as his formal reference,
( I suggested the CRT), but a sour aftertaste remained in my brain after I left the office, just wondering what makes the LCD soo blue-ish compared to CRT and how to deal with this as to be able to check the same file in both units-without pretending to make detailed color evaluations- but at least see something look-alike.
I had not dealt with LCD's before, so if there is a basic premise that I am not aware of , please enlighten me.
Any hints will be appreciated. THX!!!
