I have an RS57, Radiance 2021 and Chromapure auto-cal software. I now have 102 hours on my RS57, probably 25 to 30 of those spent on calibration (significant learning curve for a first time Radiance owner (and auto-cal user). I have previously manually calibrated a VP (VideoEQ) with Chromapure software, though I would still count myself as a calibration novice.
I successfully updated the firmware on Thursday and, like others, my HDMI handshake problems seem to have gone away. After initial startup problems, my auto calibrations have gone well, except that I can't get a good gamma curve (mostly a drop off at the high end. My post-cal deltaE's are almost always good . I have tried multiple settings for both the pj and the Chromapure software, but no success in getting a flat gamma curve. I have chalked up this problem to my inexperience, but I guess it could be the Radiance, though the smart money is still on operator error. I have always said that the only thing that has kept me from being a pro athlete is lack of talent and that same concept can be applied to calibration.
