– technicolor: unity 1dlut + unity 1dlut (full ddc reset) Well, we don’t have to think about it anymore (unless I screwed up something), yesterday I played with Calman using 2 cases:
Lg c8 lut box manual#
Cal file (if it was working) or with a manual greyscale calibration.Ĭalman lightning LUT for HDR10 … I don’t know how calman handles the clipping/rendering intent equivalent.
This should work either with the Displa圜al calibration to generate the. “absolute colorimetric with whitepoint scaling” for the rendering intent. So at least from first principles, one should try to do an XYZLUT profile in calibration mode, and generate a 3d lut for BT.2020 gamma 2.2 with e.g. Given the fact that Displa圜al/Argyll cannot exploit the fact that content is limited to the DCI-P3 subset of the BT.2020 space when generating a 3d LUT for gamma 2.2, all of the appearance/perceptual rendering intents will always apply stronger-than-necessary gamut compression. For a matrix calibration (in either Calman or Displa圜al) the colour primaries will be measured at peak brightness, which means that the matrix is only really valid at peak brightness, and any rendering intent which is applied is very likely to mess things up at lower brightness levels where primaries are more saturated, by applying stronger than necessary clipping and/or gamut compression. I don’t know how calman handles the clipping/rendering intent equivalent. Then the 3d LUT generation would correspond to BT.2020 gamma 2.2 (or unchanged). Measurements should be taken in calibration mode. This reply was modified 2 years, 5 months ago by chros.Ĭalman lightning LUT for HDR10 should be roughly equivalent to curves+Matrix profiling in Displa圜al (but displaycal will still need to take more than 5 measurements to estimate the greyscale curves for the profile). I want to try out other synthetic settings first and compare it with my current one, maybe it will act differently.ĭon’t we know what Calman does with LighningLut (when measure only 5 colors, RGBWB) with HDR10? What color gamuts are used, rendering intent, does it measure the colors in calibration mode? Sometimes I switched between the 2 presets: colors sometimes are different ( obviously), but I lost a bit brightness and overall pop, image gets less vivid.
Lg c8 lut box movie#
I watched a full movie with it (ims) and the good thing is that I haven’t noticed anything outstanding (color issues). If I just watched it without comparing I wouldn’t say anything in that sample is elevated. Switching back and forth between presets and what I mostly see is that the synthetic 3DLUT desaturates cyan and in some parts that makes it a bit brighter. Here is the new 1DLUT with corrected EOTF but I really don’t think this will match your panelĬheers, I know just wanted to try it out, I modified the first 5 entries in it (reduced the values), no cyan/magenta issue, but the overall image is still brighter, probably I have to do it myself 🙂
