HSL / Grayscale

HSL/Grayscale can be used for color correction and BW conversion.

1. For color adjustment, select a tab corresponding to the required color property - Hue, Saturation, or Luminance (fig. 1).

Then, tune the selected parameter with the "color range" sliders.

For instance, in the screenshot 1, luminance of "Blues" and "Aquas" is reduced, while luminance of "Reds" and "Oranges" is increased.

A video-tutorial on this topic is available here.

2. To make a color image black and white, check "Convert to Grayscale" option (fig. 2) and specify with the sliders how the original colors influence the resulting monochrome image.

The screenshot 2 exemplifies darkening the (formerly) blue sky and lightening the orange rock.
