I do see the argument for saturation, if you're calibrating at 75% saturation. Which isn't something we were able to do in v4.
For luminance, if you don't have enough, you should be turning white down, not the colors up.
So I can raise these values in my display, but I cannot raise these values in the Duo...is that what you're saying? That just doesn't sound right at all.
If the internal default Lightness setting for a particular color is set low in the service menu for example, I should still be able to and can raise the lightness of that particular color with the CMS lightness control since the display is capable of handling it. In fact, even if I leave the display alone, I should still be able to raise the Lightness setting in the Duo
I can work this exactly the way I want in ChromaPure and get a perfectly artifact free image with a flat grayscale from 10%-100% IRE with a gamma of 2.22, and with RGBCYM all calibrated with a DeltaE error of under 1.0 for each, all while leaving my display grayscale and CMS controls at their default 0 settings, only adjusting display's Contrast and Brightness with a Pluge pattern, and calibrating only with the Duo's grayscale and CMS controls.
In ChromaPure, I have a choice in how I want the CMS to be controlled by either HSL or xyY, or whatever. When working with the Duo, I use the xyY setting in ChromaPure, and then use the AVS user created DVDO iScan Duo Control program to change the values in the Duo to perform the calibration. I have to use the AVSHD disk to provide the patterns, which I play with my OPPO BDP-93 which I have set to Source Direct mode so it bypasses any of the player's internal image processing and passes the digital information directly from the Blu-ray disk to the Duo. This works great and allows me to easily calibrate my system and I have been pleased with the results.
My interest in CalMan had to do with CalMan's ability to use the pattern generator in the Duo to create the patterns I need to calibrate my system that ChromaPure simply isn't capable of doing with the Duo. Full field patterns for both grayscale and color, and color patterns of various saturation levels. I was also interested in CalMan's DDC controls that allow me to control my Duo from my computer without having to resort to a remote or any other external program.
If I can duplicate or even improve on the results I get in ChromaPure by using CalMan, I would be absolutely delighted.
Are you telling me that it is not possible for me to accomplish what I want using CalMan because of a limitation in how the DDC controls are implemented? Honestly, this makes no sense to me.
