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)
Long exposure Steel wool lit on fire spun on a leash while spinning in a circle. House hold item used to make a beautiful picture. Notice the distance the photographer uses to ensure perfect exposure. Too close will lead to over exposure.
