FWIW, I just written a short article on using ColorPort (instead of MeasureTool) to measure QTR grayscale targets. I've also released ColorPort XML files that allow one to select these targets within ColorPort. Those that use Roy Harrington's excellent "QTR-Create_ICC" script to make profiles for grayscale printing and alt-processes should be happy about this. http://www.on-sight.com/2012/02/22/using-colorport-for-qtr-grayscale-and-alt... My next article will directly discuss the process of profiling alt-process negatives and photogravure positives in great detail. More on that soon. Scott Martin www.on-sight.com
