Would you mind giving examples where you use parametric masking? I read the docs* and it is not very clear to me the practical side (I'm a Lightroom user).

This video shows how parametric masks can be used: https://www.youtube.com/watch?v=Hfw-GWowH9M

This is one of the most powerful feature in this software.

An example: Camera noise is often particularly annoying in the sky area. So I'll have two denoising filters active: A subtle one that doesn't lose much detail, and a strong one that only applies to the sky. Selecting the sky tends to be easy with a parametric mask: Just select the sky's hue and it's done.

I use mushroom, but these generalized parametric masks look super useful!

That said, Lightroom now let's you mask the sky with a single click.

I meant "Lightroom", not "mushroom".
