Using the Elliptical Marquee Tool
The Elliptical Marquee tool lets you create oval or circular selection marquees. When used with the Layer Mask option, and a couple of creative filters, you can create some awesome vignettes. Select the Elliptical Marquee tool on the toolbox from the available Marquee options, move into the document, and drag the tool using the mouse to control your movements. To further control a selection, hold down the Shift key to produce a perfect circle, and hold down the Alt (Win) or Option (Mac) key to create a selection marquee from center out. Releasing the mouse instructs the Elliptical Marquee tool to create the selection.
