Strobist info -
One SB800 on light stand on subject's left with home-made strip reflector (folded piece of metal sheeting), set to manual (not sure exact setting).
One SB800 from behind/below subject, fired through home-made snoot/reflector (made from food pot lined with aluminium tape, with different lids with Rosco gels glued onto them for quick colour changes. One of the best light mods I've made!)
Shot in a Soho alleyway next to some scaffolding to get the worklights as extra points of interest in the background.
Flashes triggered by Calumet radio triggers (fantastic).
Smoke's just from the cigarette.
