Thus it would be great to be able to use the CA-6X for low stimulus grayscale calibration PROVIDED so doing would improve the above noted consistency and time issue....to that point, will a profiled CA-6X be materially more consistent at low stimulus levels?
We have both xyY offset and 3x3 matrix profiling in now, though they are not well documented. We will be rolling out a regression-based approach in a point release in the future, though this will be spreadsheet-based for a while (too much UI work is in line ahead of it). The regression-approach requires us to make some additional internal changes, so there is still a little work to be done.
By the way, we do all of the math ourselves on this to ensure that it is done accurately. Excel has had bugs in its statistics libraries for years, and it is just easier for us to go straight to the raw matrix math.
b) What is the best way to use the CA-6X and i1Pro within CalMAN (i.e. CA-6X for low stimulus grayscale and i1Pro for high stimulus grayscale, color decoding and color gamut) in light of the fact that the "start up process" requires the selection of a (i.e. one) meter...or is the idea that once the CA-6X is profiled to the i1Pro to simply use the CA-6X for everything?
I would use the CA-6X for grayscale work on most displays, and then use the i1 Pro for gamut work (e.g., CMS, Color Decoder). On "odd" displays, you may want to use the i1 Pro for everything, despite its limited range.
