Hi Steve, so here is my latest run. I think there are some improvements.
First some background which I probably should have provided before....
Projector is a JVC DLA-RS540 with about 500 hours on the lamp. Projector is warmed up for a minimum of 1 hour before any profiling or verification.
Profiling meter is a Klein K10A probe matched through CS to a Jeti Specbos 1211
I am using one of the JVC filter modes (Reference mode in this case) to get a wider gamut that I can calibrate down to Rec. 709.
Final LUT is uploaded to a Radiance Pro. I am also using the Radiance to generate YCbCr 422 patches for profiling.
I used Map Space in this case for the LUT, though Peak Chroma produces almost identical results.
I ran the 21 cube profile as you suggested with a drift of 50.
Attached is the 1000pt. verification for this run as well as my grey only verification.
The Clip, EOTF, Diff EOTF and RGB Separation all look improved. RGB balance is nicer as well. I am still seeing points out of gamut around green and along green-cyan, but I think this is just a result of how this filter mode calibrates. I have always noticed some oddities with green so perhaps it is related. For example, no matter how precise my probe match is, I will start to see my K10 measurements on green deviate from the Jeti as I go even just slightly lower in luminance. I don't see this on Red or Blue when verifying the probe match.
Thanks for taking the time to look at this. I want to post these results to the web site I am building, so I would like to know how you would grade this calibration from a professional standpoint.
