Using any selection tool, click New Selection in the options bar, and position the pointer inside an existing selection border. The pointer changes to indicate that you can move the selection .
The New Selection option appears in the options bar when any selection tool is selected—except the Selection Brush tool. Switch to another selection tool temporarily, if necessary, to select this option.
- Drag the border to enclose a different area of the photo. You can drag a selection border beyond the canvas boundaries; however, this makes it hard to get back. You can also drag the selection border to another image window.
Inverting a selection changes the unselected areas into selected areas, protecting the area you previously selected.
You can add to or subtract from an existing selection to fine-tune selection borders. For example, you could make a donut-shaped selection by first making a circular selection and then subtracting a circular selection within it.
You can limit the area a selection affects. For example, in a picture of snow-capped mountains, you can select white clouds in the sky without selecting parts of the white mountain below them by selecting the entire sky, and then using the Magic Wand tool with Intersect With Selection selected and Contiguous deselected to select only the white areas included within the existing sky selection.
You can use commands in the Select menu to increase or decrease the size of an existing selection and to clean up stray pixels left inside or outside a color-based selection.
The Border command creates a soft-edged, anti-aliased selection border. When you add the new selection border, only pixels between the two selection borders are selected.
The Smooth command searches around each selected pixel for other pixels within the specified color range and selects them.
When you move or paste a selection, some of the pixels surrounding the selection border are included with the selection. These extra pixels can result in a fringe or halo around the edges of the selection. The Defringe Layer command replaces the color of any fringe pixels with the colors of nearby pixels containing pure colors (those without background color). For example, if you select a yellow object on a blue background and then move the selection, some of the blue background is moved with the object. Defringe Layer replaces the blue pixels with yellow pixels.
