A little movement
So this is singer Nicki Rogers surrounded by what appears to be a million mental fireflies. That or a series of hippies are using tracer ammunition. This is not, however, an effect courtesy of photoshop. On the night in question she was sitting in front of a wall covered in fairy lights. The combination of a slow shutter and tilted flash set to fire at the end of the exposure along with a jaunty twirl of the lens meant this was achieved in camera. Which is always some kind of result I think.
