Forced perspective is a technique that employs optical illusion to make an object appear farther away, closer, larger or smaller than it actually is. It is used primarily in photography, filmmaking and architecture.
Wrap lights around and turn the picture unfocused and it creates beautiful bokeh:) I do this a lot but just on Christmas trees. Also with a natural light in the back, wonderful contrast with the green dress. Just a great picture!
Bokeh photography: Manually focus everything so the lights in the background are out of focus, and the subject (if there is one) is in focus. Also keep a small depth-of-field with a small aperture so the background is easily blurred (motion blur)
