3 In the Brush HUD, click the Feather button.
Click the Feather button.
4 Specify the diameter of the brush and its intensity using the Brush Size and Strength sliders and
value sliders.
5 Drag the brush over the edges of the previously applied brush strokes.
Tip: When feathering brush stokes, it’s a good idea to display the brush strokes as color overlays
to help identify the boundaries of each brush stroke. You can turn the color overlays off at
regular intervals and visually inspect the image to ensure that the brush strokes are feathered
appropriately. For more information, see
Work with brushed adjustment overlays on page 235.

image instead.

Inspector HUD, and click the Brush button in the adjustment controls.

pop-up menu.
Erase brush strokes
You can erase the brush strokes for a previously applied brushed adjustment using the eraser
brush in the Brush HUD. The eraser brush erases the brush strokes of the selected brushed
adjustment only. The eraser brush uses the same parameters as the standard brush (Brush Size,
Softness, and Strength).
Tip: You can quickly switch from the brush to the eraser by holding down the Option key. To
switch back to the brush, release the Option key.
