LR2 camera calibration results - 40D, DS & K-m/K2000

[wlachan]

I have just done calibrating my own cameras for LR2 using the PS script AcrCalibrator 1.2. My goal was to produce consistant colours from all 3 bodies. It was done using the FA31 w/o filter. Tungsten was done at 2800K. Obviously every camera is different but if anyone aren't too happy with the LR2 default, you might try these instead.

On the DS, I see there's a huge negative Green Saturation number. Does that mean that it needs to be pulled back significantly in order to be more accurate? That would kind of fit in with how people tend to praise Pentax for having such strong greens in the images.

I guess it must be because I compared the calibrated shots with the actual ColorChecker, they look pretty close in colour. I remember I experienced some neon green in some shots in the past, but I haven't done much landscape to be certain it had to do with the green saturation.
