Everything including the kitchen sink.
This is my first ever go at fast flash photography, and I have got to say I had a ball learning something new!
I have a heap of possible entries, and can't decide
... so this is my interim entry. If I find John West has made a mistake I'll swap it.
Olympus E510, FL50 flash, tripod, kitchen sink, dripping tap, plug in hole, no cable release, auto focus, 100ASA, 1/30 sec, f/5.6, 12-60 zoom at 56mm, manual flash on GN9.5. I did heaps later with cable release and manual focus... great fun
