Adjusting selections manually
You can use the selection tools to add to or subtract from existing pixel selections.
Before manually adding to or subtracting from a selection, set the feather and anti-aliased

.)
To add to a selection or select an additional area:

Using any selection tool, do one of the following:
•
Select the Add to Selection option
in the options bar, and drag.

Adjusting selections numerically
You can use commands in the Select menu to increase or decrease the pixels in an existing
selection and to clean up stray pixels left inside or outside a color-based selection.
To expand or contract a selection by a specific number of pixels:
1
Choose Select > Modify > Expand or Contract.
2
For Expand By or Contract By, enter a pixel value between 1 and 100, and click OK.
The border is increased or decreased by the specified number of pixels. Any portion of the
selection border running along the canvas’s edge is unaffected.
To frame an existing selection with a new selection:
1
Use a selection tool to make a selection.
2
Choose Select > Modify > Border.
3
Enter a value between 1 and 200 pixels for the border width of the new selection, and
click OK.
The new selection frames the original selected area.
