Vignette

The image on the left is my original image. I then selected the Elliptical Marquee Tool so it created an oval shape in the middle of the image and then i right clicked and chose 'select inverse'. I then clicked on the paint bucket and chose black and then clicked on outside the oval and then clicked 'command' and 'd. I then selected filters, blur and gaussian blur and changed the radius to 20.4 pixels which softened the black line of the oval.
