Bokeh
Few things will make the subject in a photo stand out more, than an image with great bokeh; this, of course, is just my humble opinion. Bokeh, in photography, refers to the amount of out-of-focus, or blur, within the image. The blurred area is generally achieved by setting a shallow depth of field (DOF) in your camera lens, which in-turn delivers a pleasing background either behind or in front of your subject. A larger aperture (smaller f/stop number) will provide a more shallow depth of field - the bokeh on this shot was obtained by setting the lens aperture at f/5.6
