I used a Spyder3Elite colorimeter and an i1Pro as the reference spectroradiometer. I compared created profiles only. For example, Green stimulus in each profile: i1Pro: x=0.2279, y=0.6863 Spyder3Elite without correction: x=0.1987, y=0.6556 Spyder3Elite with my correction matrix: x=0.2270, y=0.6899 Spyder3Elite with correction matrix from the list of contributed ccmx files: x=0.2540, y=0.6872 > > P.S.

Then I compared profiles in GamutVision. For Green stimulus: i1Pro: x=0.2252, y=0.6895 Spyder3Elite without correction: x=0.1954, y=0.6585 Spyder3Elite with "generic" correction: x=0.2173, y=0.6888 It isn't a great result, but it is better than nothing.
