I decided to let the 580EX off the leash today and let it flash for fun. Usually it's consigned to marshalling duty on top of my camera while the cheeky whippersnapper 430EXII's do all the glory work.
Bit of a pants shot this, if you ask me, but it's late and I'm tired - just has my tea and want to be in my bed.
Just random lighting gear that I've accumulated over the last couple year or so...
Strobist: Well, one 580EX on-camera doing it's thing. Couldn't say more than that. Pow!
