A test gradient loads by default so you can see the masks working immediately.

Zone (Ansel Adams)

Target Zone V

Zone V \u2014 middle grey. The pivot of the scale.

Width 1.0

How many neighbouring zones feather into the selection. 1.0 selects mostly the target zone; higher spreads the mask wider.

Mask Shape

Strength 1.00

How fully the selected zone is masked.

Spatial Mask (2nd mask)

Add a second mask that selects by position, then choose how the two combine.

Combine

Add selects wherever either mask reaches. Intersect selects only where both overlap \u2014 that is what lets a rough brush stroke hit only the tones you targeted.

Adjustment (through mask)

Hue 0\u00b0 Saturation 0 Lightness 0

These HSL changes are applied only through the mask \u2014 switch View to Result to see them land on the selected zone.

View

Overlay Colour

Mask shows the selection on your image \u2014 the stronger the colour, the more strongly that pixel is selected. Magenta is used because it almost never appears in real photos.
