Hi Andrea, It's been a long time since I recalibrated my monitors, so I've kind of forgotten the procedures... I also use Argyll CMS with DisplayCAL, my colorimeter is an i1 Display Pro. I don't go through the 1D LUT curve generation. Instead, I choose the "as measured" option for the white level. I set the monitor brightness to my liking (rather dark like the environment of the room concerned), directly by the monitor controls. In my case, I chose the "Rec. 1886" tone curve even though my monitors don't really have the qualities of real monitors dedicated to color correction. I like the very smooth result and I find that I can pretty well evaluate what the video will look like when presented on a TV. Pierre Le 22-07-07 à 02 h 28, Andrea paz via Cin a écrit :
Hi, I don't know how many users do monitor profiling (I remember an old discussion with Pierre...). It has been a long time since I did it but now that I tried to do it again I have unsatisfactory results in terms of brightness. The DeltaE is great (0.35) but the gamma is really high, such that it hurts the eyes after a short time. Also, the custom calibration disables the brightness/lightness OSD controls so I can't lower it. I used the Rec709 color space which has gamma 2.4 instead of the normal 2.2 value of the sRGB space. Actually with a higher gamma you should get darker results. My monitor (Dell UO2716D) is a wide gamut type and natively supports various color spaces: sRGB; Rec709; AdobeRGB and DCI-P3 (98%). It should have no problem with Rec709 at gamma 2.4. Can you explain why I get too bright a result? I use Argyll CMS with DisplayCAL and Datacolor Spyder5 colorimeter.
