Selecting the parts of images to edit is an important step in your workflow. By creating a selection, you can edit an area while leaving the rest of the image unchanged. You can use drawing or painting tools to modify selected areas of your image. You can also apply commands to flip, copy, crop, or perform other actions on the selected areas.
The border of a selection is identified by a selection marquee, which is a series of black and white dashes that outlines the selection.
