lum vs chromatically

Hi all. Who knows what can replace the curve (as in rt) “luminance according to chromatically”?
As a temporary solution, I use the channel mixer (primaries correction mode), where I increase the red saturation in the red channel and reduce the saturation in the green. This method helps, but only for red colors. There is also an option with equalizers (color equalizer > L), but the option is quite rough. The “luminance according to chromatically” option is still a very beautiful solution. This is how to weaken the saturation in the HSL model and increase the color saturation in the HSV, at the same time (davinci resolve). The result is more elegant.

How about using Highlights, Mids, Shadows adjustment with chromatic parametric mask in Color / tone correction.

Yes, thank you.

What an awesome program this is…

What an awesome program this is. I have already been using it for about 10 days and have done a lot of work using this application. The app is a fairy tale, I’m not ashamed to say it. Although I very rarely praise anything.

RawTherapee is more technical oriented and has more experimental modules and parameters, however ART is more suitable for photography enthusiasts. ART has more symplified UI than RT, however I don’t think ART is degrated technically. It isn’t a fake version of RawTherapee.

And I also think lenses of Sigma are not bad. Sigma is manufacturing not only its own lenses but also OEM lenses for other camera manufactures. :wink:

I did not know that - is there a link to where it says that?

[edit] AI claims that:

Perhaps not doing it now …

For example, please see following article.

Thanks for the update …

And yet, using the saturation histogram mask does not produce the same effect as the sat vs lum curve.
According to the curve, the effect is as if I raised the saturation in the HSV color model, and lowered it in HSL - there would be a kind of color compaction effect.
The situation is similar with the curve (specifically at rt).
Brightness and saturation are interconnected things, and just imagine - we change the brightness using the saturation mask, but brightness has its own rules regarding saturation. This is probably why the result is completely different. A mask will not work in this case.
