Well, sharks - Caribbean Reef Sharks to be precise - were probably the marquee critter on this trip, so we might as well get right into them now.
The other diver in this shot is our friend Jim (or "Ferris"), and as the two of us lined up to take shots of this shark, I thought it might be cool to show another diver in the frame. It also helped that I was shooting with the Sigma 10-20mm super-wide-angle lens to let me get plenty of stuff in the frame. What that lens didn't help was maintaining size perspective as it compressed a wide area into the frame making the shark (which is probably about 15 feet away from us) look much smaller than it was (probably about 6-8 feet long).

Technical Data: Canon EOS 7D, Sigma 10-20mm f/4-5.6 EX DC HSM AF at 14mm, 1/120 sec at f/5. ISO 400. Ikelite Housing and Port with dual Ikelite DS 161 Strobes in eTTL mode. Raw conversion Adobe Camera Raw.

There's plenty more to come, so stay tuned...
