I have a Sony 65ES projector (with <1000 h lamp life) and a Lumagen Radiance.
I'm struggling with the calibration and 3D LUT generation. I don't understand what I'm doing wrong since I succeeded to calibrate my TV with the same procedure.
I have first uploaded a null cube in the Radiance.
I use the I1DisplayPro OEM probe. In the Setup Options, I set Integration Time to 1.5 s and AIO Sync Mode. I used the Calibration Settings "Projector" and activated "Average Low Light Measurements" tick box.
- I don't understand the difference between Projector and Generic CMF?
I have set the best possible settings of the projector. Using the white calibration patch I set the colour temperature the best I could, using RGB gains (-30 Blue and +30 Red; I know the rule of thumb of only decreasing the gain values, but RGB balance exhibited a huge excess of the blue component so I also increased the Red gain).
I have made a pre characterisation using a 11^3 cube.
- Despite the colour gamut is narrow, the report exhibits a 98% coverage, is this normal?
- Should I enable the Colour Sub-Space?
I targeted a Rec709 space with a 2.2 Gamma.
I converted this Colour Space using the Fit Space algorithm.
- I see no difference in both the 3D cube and 1D graph using the Disable Gamut Mapping option, is this normal?
Finally, I uploaded the 3D + 1D LUT but the image looks green. This is confirmed by the RGB Balance measurements on the post characterisation Profile (Primary only).
Thank you for your help.
