I have been an amateur above-water photographer all my life, and finally took the plunge, so to speak, on a sailing trip to the BVIs. I had a Canon S90 and bought an Ikelite housing for it. I decided to go simple at first and shot available light while free-diving. Here are my two favorites: an octopus was nice enough to pose for me.
