Hi Mike,

I measure a gray target with my Eye-One Pro (using a given set of ABW
settings in the driver) and have written a custom software program for
building an ICC profile from the measurements. It is quite similar in
spirit to Roy Harrington's create-icc (which comes with QTR). However,
I wrote my own so that I could experiment with different ways of
remapping the tones in the output.

For instance, I originally thought that a simple linear scaling of
lightness (L*) to the media's output range would be sufficient, but
some of the research shows this isn't the case (not intuitive to me).
