This was created without using any Photoshop effects. Basically battery-powered bridal string lights hanging down from a home-made variable speed mobile (like the nursery kind) and a hula hoop on the bottom holding the centrifical forces in. Setting the shot, the model ducked into the circle, I turned on the mobile, set the camera at 1 second shutter, stood on a ladder beside her and hand triggered a remote flash manually while she posed.
This has always been one of my favorites as I love creating lighting gadgets.
