Well, I finished my calibration work..., at least almost finished I think. I may still go back and fiddle with Living Room and Dynamic settings some to get more light output, but might wait a few days. While I think I am going to be happy with all this calibration work for my movie viewing in either Natural or Theatre Black 1 calibrated settings I have derived, I wont know for sure until I get a chance to watch some Blu-ray movies, which could be for some time now that we are in the heart of football season. Also, I am starting to wonder if my eye-one is actually very accurate for red level readings (read on to see why I mention this).
The final calibration files do seem to indicate I have pretty good calibrations for TB1 and Natural, but I am no expert. With TB1 I did have to go back and re-do gamma, brightness, gamma, brightness, etc. since they clearly impact each other, etc. Took longer than I wanted (since I observed after initial gamma settings that I no longer had enough brightness. In the end, my brightness had to be moved higher by 3 clicks from -10 to -7 and then the gamma had to be redone to get back to 2.22. But, like Natural, TB1 lines up very well with all of the specs that are being used as guidelines now in the calibration output files.
Now, my level of comfort with my Living Room and Dynamic modes is another story. In fact, my observations make me wonder if either I have a bad eye-one, or if you just really have to cool down the images from Living Room or Dynamic modes like Dan said he does. While my Living Room output files herein attempt to get to 6500, the Dynamic attempts to get to 7000 and used the lower red suggestions from Dan (i.e. R=89%, G=102%, B=102%). But now I am wondering if I need to go with the more aggressive plan of R=79%, G=105%, B=105% and 7500 color temp for Dynamic, and use that same approach, or minimum of R=89%, G=102%, B=102% and 7000 for Living Room. A couple of observations cause me to suggest this, which I will list below:
1) I first noticed as I continued to crank down contrast (so that I did not run out of red and I could get better RGB tracking and better luminance tightness) that the white contrast pattern on the AVSHD disk started showing pink to red hues. I took note of it but moved on.
2) My light output in these modes (note all my work so far is in low lamp mode) is a bit better than Natural, Living Room being more than Natural and Dynamic more than Living Room, but not even close to what the original settings were and not even close to Knds Living Room Low Lamp calibration I used as a reference point from post #294. Knd's Y output is much higher, since I measured a complete calibration set of output files for his settings on my pj and my environment. In fact, his output for Living Room is much higher than mine for Dynamic because his contrast setting is so much higher. I have posted below all relevant .chc and Excel gamut files (Dans file) for my current Living Room, my current Dynamic and also Knds post #294 settings as inserted in my projector. Stereomandan and Knd please look at these and tell me any insights you have. Knd, please tell me how these full output files compare to your output files from post #294 (not sure I ever saw the .chc or excel files posted) [Note, I have used Dans hue trick for green on the Dynamic calibration but have not gone back and done it with LR yet because I might have an entire fundamental change of strategy in so far as RGB values and color temp to pursue after I get comments on this post].
3) Anyway, the output files seem to indicate my calibrations for LR and Dynamic are quite a bit better than Knds settings on my system and environment. However, with that said, I dont think the picture I have gotten out of my LR and Dynamic calibrations is a lot better than the one derived from Knds shared settings from post 294. Color accuracy is likely a bit better to the eye, but it is not a huge difference to my eye. While his settings on my pj suffer in red value and also luminance tracking (and the colors dont look to track as well), I have not noticed significant effects in football watching (like I did with the out of the box greens on the RS1 that I sampled once). Also, when a white screen is projected I then notice that his settings produce a white that looks much more correct than my Dynamic or Living Room settings that seem to have way too much red/pink in them. (just like noted in the AVSHD white pluge pattern when I had to crank down contrast so far to get luminance to tighten and track)
Please tell me if you guys can make any sense of this or give me a recommendation. Should I go back and turn my contrast up on the white pluge contrast image to where I don't see pink, and then just pick a cooler color temp and less Red in the gray scale throughout? In general, I can live with the PQ overall from my LR, Dynamic and even Knds LR mode....the latter giving me a sense of comfort that my whites wont look pink, but the colors not being quite as accurate When I flip back and forth between them I cannot see major difference betweens my LR and Dynamic in real life, and Knds LR setting either...though the latter is clearly brighter than even my Dynamic settings due to my low contrast and might be a bit over-saturated in a few color areas.
In the end, I am wondering if either my sensor is just way off in not being able to be sensitive to red (and therefore when all my files say I have reached an optimum calibration I really have too much red), or if I just need to get much more aggressive on the cool side...choosing higher contrast in Living Room with R=89%, G=102%, B=102%, color temp of 7000; and even higher contrast in Dynamic with R=79%, G=105%, B=105% and color temp of 7500. (and, is this correct? that r=89%, etc. is matched to color temp 7000 and r=79%, etc. is matched to color temp 7500....)
Thanks for all your help along the way. I think I am nearing my completion of calibration work at this stage of bulb lifecycle...though, I am feeling like I have not "nailed it" as good as I can yet for LR and Dynamic insofar as finding that I have got it set as good as possible for balancing the "PQ to the eye" and the calibration "as measured by the equipment."
