OK so i tried calibrating with RC1 and to start, the results look better to me from the last Beta since Tyler took D-Nice's and my suggestion to do additional Grayscale scans. Now Autocal does what they call a "rolling" calibration in the final scan. From what i can see, Autocal once it completes the first scan, goes back and looks at and re-calibrates IRE triplets, if that's the correct term. So for example it will "touch-up" IRE's 99,105, 109, then the next three down until it gets to zero. This seems to fix some of the spikes from the first scan giving a little better results. The other observation is by default, the DeltaE target is set to 0.5. This usually takes about 10 minutes to run. But if i set the target to 0.2, then i runs for about 30 minutes and while there is improvement, i'm not sure it's worth the extra time.
The only other issue i have is although the DeltaE errors are all under 0.5 with an average of around 0.2, there are still some noticable spikes and or dips in the gamma curve. Tyler indicated he was going to explain what we are seeing and i hope he does since while they are not large errors, they are still there.
Below are screen shots of the Technicolor calibration i did this morning. Please note that i opened up all scale on all the graphs to illustrate as much detail as possible. All default values, Gamma 1886. 42 pt gray scale and lightening LUT. DeltaE target at the default of 0.5. The whole calibration took around 30 minutes to complete everything. I also took the low stimulus scans that everyone wants to see and all i can say "it is what it is".
The last set of scans are from an Expert Bright PM calibration with Gamma 2.2. 42 pt grayscale and lightening LUT. Here the DeltaE target is set to 0.2 and the whole calibration took about 45 minutes, complete, not rushing.
One thing to keep in mind is that the PMs i used this morning are both Bright PMs and can be more challenging to calibrate. In conversations with D-Nice, he indicated that he is getting better results with the Darker PMs in the 100-150 nit range.
As far as the CMS sweep and color checker scans, although not reference montor quality when you add in all the details, any set where the CMS sweep and color checker DeltaE is at or below 1.0 is good in my opinion. Notice that there are essentially no spikes in the sweeps and or the color checker. I hope D-Nice can come up with an iRP setting that does better but doesn't take hours to run.
So next we will be waiting for D-Nice's indepth review with, i'm sure a whole lot more technical information.
My conclusion so far is RC1 is giving "better" results than the last Beta which is incouraging and i'm happy that some of our Beta feedback was considered
