Mike's CMS Calibration Notes

The color gamut by default was pretty accurate.  Red, blue and magenta had the highest gain and saturation errors pre-calibration, while cyan was off a bit in hue.  Green and yellow, often the most inaccurate colors with many DLP projectors, were both quite good by default.  The CMS worked well, bringing the Delta E error down from a 3.9 average to 0.6.  Chromaticity errors, which ranged from -14% to 12.5% were also reduced to a range of -2.3% to 2.1%.
