By blurring the background by DepthField all attention is moved toward the main component of the photo. Different kinds of blurring mode are allowed on the out of focus region, you can change the blades (angles) or even use a custom image as a blurring kernel. DepthField works also in a more subtle way. You do not blur the background but you increase the sharpness of the subject in focus.
