Inverting selections

You can invert a selection, which deselects the previously selected area and selects the

previously unselected area.

The marquee indicates that the flower is selected (left). After inverting the

selection, the marquees, that surround both the canvas and the flower, indicate

that everything but the flower is selected (right).

A pixel-based selection can include 256 values, like a grayscale image. An inverted

pixel-based selection is equivalent to the negative of a grayscale image. For example, a

pixel that has 80% luminance will have 20% luminance when inverted.

To invert a selection

1 In the toolbox, click the Selection Adjuster tool , and then click a selection.

2 From the menu bar, choose Select  Invert Selection.

To produce a unique effect, you can nudge the selection by a few pixels by

using the Selection Adjuster tool, clicking the selection, and then pressing

an arrow key on your keyboard a few times. This technique works only when

the selection is directly on the canvas, it does not work if the selection is on a

layer.

Softening the edges of selections

You can soften the edges of a path-based selection by anti-aliasing or feathering. Anti-

aliasing smooths the edges of a selection by modifying the color transition between the

pixels. Feathering, on the other hand, softens the edges by gradually increasing the

transparency of the pixels along the edge of the selection.
