Yes, coming in a fix in January.
Is it possible to automatically set base primaries as sRGB instead of the Rec2020 when AgX is set as auto-applied workflow default?
Yes, it’s possible, simply create an auto-applied preset.
However, it may have drawbacks (the pipeline input will be converted to sRGB, and colours that don’t fit into that space will be pushed inside the gamut in a lossy way, potentially creating artefacts). Even if you do that, because of the post-curve primaries adjustments and saturation adjustment (if you use them), the final colour may end up outside sRGB.
The N6 effect is also stronger with a small space. You may want to increase the pre-curve attenuation (also helps with the path to white) and/or use higher hue preservation (helps with the N6 skew).
Any particular reason you want to use sRGB? According to Eary Chow, one of the original Blender devs, larger spaces often work better if you have difficult lighting.
Unfortunately, this comes from my misunderstanding. I thought that since I worked in sRGB, it was better to play with AgX in sRGB (it was to some extent confirmed by one of YT videos I watched). After your explanation, I had a look at the pipeline and there is another module (output color profile) at the end that converts it to sRGB.
Sorry for that question and thank you for your clear answer. I do not need what I asked for…
If you guys think “well, that christmas tree could be a bit more towards green” - would you use the primaries rotation or reverse rotation?
For ‘artistic’ tweaks, always reverse rotation and/or purity boost.
I would use some other module, to be honest. The primaries in AgX serve, I think, mostly to steer how highlights are treated.
May I politely suggest a subtle amendment to the after tone mapping section of the user manual.
This currently reads… “reverse all : Ticking this checkbox will hide the other controls in the group, and adjust processing settings as if the master reversal sliders, discussed below, were set to 100%”.
In the following paragraph you refer to these as master controls, which makes more sense, and avoids confusion with other reversal sliders.
