I forgot to mention this. If you are building the profiles from the ground up you can skip the linearize= line and use one of these correction curve tools instead. Other people have found this to be better than the linearize function in the QTR app: http://www.bwmastery.com/qtr-correction-curve-tool Hope that helps, Richard Boutwell
