JRVR > Calibration > 3DLUT Gamma (tone curve) - what is it?

<< < (8/12) > >>

mattkhan:
displaycal will show you the relevant curves that are available to the 3dlut, as far as I can see, those are linear

mattkhan:
any idea how to look at what is actually loaded in windows?

mattkhan:
I used the displaycal profile loader to force it to reset the gamma tables for "Media Center 31.exe" and remeasured, same result so I think that rules that out (though would be nice to be able to "see" what is loaded directly somehow so I can be sure)

Hendrik:
Looks like displaycal always make ArgyllCMS apply the calibration to the 3DLUT, and write a linear gamma ramp. So I guess I don't need to worry about supporting that for now.

mattkhan:
I generated a new lut with the vcgt turned off, loaded into both jrvr and madvr & remeasured, same result (low end rolloff in jrvr) again
