Manipulating Images 91
To modify a current selection:
1. From any Selection context toolbar, select Modify Selection.
2. From the Modify Selection dialog, you can enter a specific pixel value for
the type of operation you require.
• Feather: Use to apply feathering to the edge of an existing
selection (but before applying any editing changes). Enter the
width (in pixels) of the transition area. A higher value produces a
wider, more gradual fade-out. See Soft-edged and hard-edged
selections on p. 93.
• Smooth: If the selected region has ragged edges or discontinuous
regions (for example, if you've just used the Magic Wand Tool),
use the option to control the extent of smoothing.
• Contract/Expand: Move the slider left to contract (shrink) the
borders of the selection, or right to extend its borders.
3. Select a preview method from the Preview drop-down list—choose to
preview as an Overlay, in Grayscale, or use different Mattes.
