Off camera flash and underwater photography

I've been involved in a project with Alex Mustard in using slave strobes to acheive an off camera type effect. We took some pictures at Capernwray last Wednesday, and I ws amazed at the results. We used a combination of a Heinrichs Weikamp slave strobe adaptor that triggered a Sea and Sea YS30 and in turn two big Subtronic strobes. In fact though I brought along a Firefly 1 slave set up, designed for use in dry caves, and put it into an Otter box. The results were excellent.I'll post some pictures here soon
