Hagar, what we are interested in comparing is the linearity
of the CMS: The VideEQ and Radiance have (currently) only a single point adjustment for the CMS. Therefore it is possible that at different saturations the measured results (using either Calman, HFCR or Chromapure) could be different for each CMS solution at points other than those that the calibration was done. When I calibrated with my VideoEQ I used 75% patterns, for example. It could be that there is an error at 100% or 50% and it may vary dependinig on which CMS you use (even if the 75% calibration measures exactly the same with either CMS).
I plan to use the Mini3D for greyscale, gamma and CMS into my HD350. I could then copy this setting to a spare memory and clear the CMS. I would then add my VideoEQ into the chain and only adjust the CMS settings (so both results use the same greyscale correction, which I would also check with the VEQ in and out of circuit for consistancy). As Lumagen recommend calibrating the CMS at 100% I would also set the VideoEQ using the same 100% patterns for consistancy.
If anyone has any further comments regarding this methodogy please let me know as I plan to recalibrate my projector tomorrow night, so I might be able to perform these checks then or on Thursday night (OH out of town
