HSL Qualification Controls
The HSL Qualifier is by far the most versatile mode of the Qualifier palette. It’s also the qualifier that’s easiest to understand, and the easiest to adjust by hand if you don’t feel the need to sample the image. By selecting range and softness for each of three different color components, hue, saturation, and luma, you can isolate a wide variety of colorful subjects, or ranges of image lightness and saturation.

One of the HSL Qualifier’s key strengths, and one of its most underutilized features, is that you can enable or disable each of the three HSL components using the Hue, Sat, and Lum buttons, using toggle controls found at the left of each qualifier range control’s name. This lets you ignore specific color components, while focusing on others that are more important.
For example, if you’re trying to isolate the saturated parts of an image, regardless of the hue or brightness, you can turn off the Hue and Lum qualifiers so that only Sat is used to sample the image.
