Masketta Fall get the Harry Potter look!
You can see flare from one of the lights creeping into the shot on the right edge of the pic, about 3 metres down the alley. The other light was to camera left. Both lights were Sunpak 383's on stands triggered by Skyports, and snooted with the empty rolls from toilet paper. Snooting the light makes it appear more dramatic. The Sunpaks were set to full power to overcome the ambient light. (it was the middle of the day)
The toughest part was making sure everybody was lit by both strobes.
