Also, in the Luminance section, it’s safe to make the blue and cyan darker to darken the sky and make the clouds pop. These actions have the same sky-darkening effect as a polarized filter.
The important thing here is that when you darken the colour, its saturation increases. So, after darkening, navigate to the Saturation tab and decrease it for the same colours.
Another cool tip here is to use the Targeting tool. Select it, click anywhere on the photo and drag your mouse to the left or right. It will pick the proper amounts of colours and change the sliders accordingly.
