- For my last calibration, I left FALD on and calibrated tediously to get the grey scale dialed in while it was turned on. Pain in the neck, but delivered awesome results. This time, I turned it off. Still debating whether to calibrate the brightness at 100 with it on, then turn it off and adjust, then turn on, or just calibrate with it off and leave it off.
The reason I set to override black level at 0 is that to adjust the green at each gray level, thereby adjusting the Y, each time I adjust it without override, it changes the black level higher for zero, thereby throwing the lower scale off on Y and having to start over in a vicious circle. What do you do for adjusting the Y level for gray scale calibration on Y?
So, my current technique is meter centered, 100 amp 100 sat white reading for backlight to 120 cd/m2, brightness setting, contrast setting, two-point by setting offsets and gains, recheck all to this point, 10-point gray, then color, including 10 point saturation and either 4 or 10 point amplitude for brightness, giving more emphasis to saturation than brightness. I then go back and reset 10-point again and adjust color again, rarely touching the offset or gain at this point (unless necessary). I check 10-point one more time, then do a skin tone color check, usually calman, sometimes add pantone as well.
This last time, I sent the signal in RGB instead of YCbCr, which may be part of the issue. I did it with FALD off, but as I said, likely the player. If you could give suggestions on how to deal with adjusting the Y level when not overriding, that would be wonderful, as well as any other issues you see in my technique...
