This is one of my favorite pictures. We were able to achieve this effect by having a very slow shutter speed, at the time we took this picture it was 4 seconds. The aperture was really close as well, for this picture we used F13. These settings work because we had really low light with the exception of the flashlights and the flash itself, also the shutter speed was really slow so the movement of the flashlights was captured. I like the fact that in this particular picture it looks like the colored lights are actually going around her.
