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".
