Yeah, I must say, it's laughable that advertisement states that the MacBook Pros are great for on-the-go digital photography... they should add the tag line: "just don't do any color editing on them".
So, the larger assumed gamut of our canned profiles meant that certain colors that our monitors *are* deficient at reproducing (e.g. yellow) were NOT being pumped out at higher values/saturations by color-managed software. However, after calibration with the i1, the limited gamut monitor profile instructed CM applications to heighten yellows before sending to my MBP LCD screen... hence the more reasonable colors (less over-blown saturation in the oranges/reds) after calibration with the i1. This is also obvious when I drag the LR window from my MBP LCD display to my Sony CRT: Initially, on the Sony CRT, the image in the incoming LR window (as I'm dragging it over) appears intensely yellow (i.e. the image that was being pumped to my MBP LCD was oversaturated in yellow, since my MBP LCD was inefficient at displaying yellow)... then as CM kicks in for my Sony CRT, oranges are restored as yellows are brought back down.
So, I still prefer my i1 profile over the canned profile.
But only for pictures without blues, I guess, since it turns blues violet. *SIGH*.
tlooknbill, don't you think it's funny, though, that your Pismo PowerBook monitor profile generated by the i1 says that your dinky laptop screen has a larger gamut in the blues than your iMac screen?
HIGHLY unlikely, and I still stand my ground that this overextension in the gamut of blues in these i1-generated profiles is more-than-likely what is causing the blue-to-violet hue shift for Andrew F., Andrew W., and me (& probably others who just haven't noticed it yet!).
Any theories? Contact i1 tech support? This problem has *got* to be fixable.
