Zombie84, thanks for the feedback, I was thinking the corrected shots looked a little too green/cyan, so thanks for confirming that. ;)

Moth3r to answer your question, yes I have done a basic calibration of my display, well actually I have done as advanced a calibration as Mac OS will allow me! I am running Windows XP SP3 in a Virtual Machine at present.

Here are some updated comparisons using Zombie84's suggestions for settings adjustments.

Here are the latest settings I am using for colour correction:

ColorYUV(off_u=-1.0,off_v=-2.29).Levels(15,1.08,255,0,255).Tweak(sat=1.2)
