Hi all, always an interesting topic: color calibration. i just got a new mbp and i am a designer on a tight budget, so no spyder or colortron for me! the first thing i noticed when i switched from a pc desktop (which was calibrated by eyeball and fairly matched with samsung 720b external flat screen, lide35 scanner, and i905d printer) was the gamma was off. the apple 1.8 gamma setting seemed to bright for the new mac backlite led lcd. so after using color sync calibrator, i get a gamma of 2.199 and that matches the samsung external at the 1.8 gamma. All of which now pretty much matches the setup i had before, used a lot for color printing of photos and graphics, as well as web work. it's all pretty rough, but close enough for government work, which i do.
The supercal program does not seem to be updated to include the new mac screens, but perhaps that's just a labeling issue. a response curve calculator is a response curve calculator, i think, and the results should be the same using that and using colorsync. In the end, it comes down to the gamma setting which i find the apple 1.8 to be very strange on this mbp. hmmm....
ps. for designers: the bergdesign website is really interesting, with a few free plugs for PS Cs3. the maskerade program there is really interesting...a fresh take on masking.
