Bruce,
I too thank you for your tutorial. I have used it to produce a profile for my Canon 10D that I find better than the default (I just knew buying that Gretag MacBeth color checker last year was not a waste of money :) )

I did have a problem following one of your steps and "invented" a solution for it. Everything went fine until the part about using the saturation slider in the adjustment tab to bring the green channel of the green square. In order to get it down to 123 (I used Prophoto - which is actually my default working space) I needed to do a massive desaturation which, of course, brings up the value of the other 2 channels up quite a bit. Another option would have been to lower the Exposure setting and bring it down that way but that seemed like a more drastic change than what I eventually did: I left the green channel at 128 and increased all target values by 4%.
After doing that all the calibrate adjustments went smoothly and, as I said, I ended-up with something that is visually better than the default.
Could I have done things differently to produce a more accurate calibration?
