Instant Artistic Effect: Just add Edge Vignette
Anyone can take a picture and give it more of an artistic feel using vignetting. In the Lens Correction dialog (Filter>Distort>Lens Correction), there is a setting called Vignette that’s used to correct problems with lenses that darken the edges of a photograph. It can also be used to add vignetting to a picture for dramatic effect. Drag the Vignette Amount and Midpoint sliders to the left. In a few seconds, your picture will look just like the pros.
