I  love shooting digitally.  Cranking up the ISO at night is a revelation with a good digital camera, giving quality you just could never get with film. I pushed the ISO to 2500 for this image, giving me just enough shutter speed (1/4 second) to keep the dancers slightly ghosted and the spectators fairly sharp.  I love that combination of motion and stillness and shot about 20 frames until I got one I liked.
