Modify the range of Hue/Saturation effect adjustments
1 From the Channel Control menu, choose an individual color. (By default, the range of color selected when you
choose a color component is 30˚ wide, with 30˚ of fall-off on either side. Setting the fall-off too low can produce
dithering in the image.)
Do any of the following:
2
• Drag one or both of the white triangles to adjust the amount of feather without affecting the range.
• Drag one or both of the vertical white bars to adjust the range. Increasing the range decreases the fall-off, and vice
versa.

The Leave Color effect removes all colors from a layer except those similar to the Color To Leave. For example, a
