From my diving days and old scanned slide taken around Andros in the Bahamas. No recorded info but sure it was made with a Nikonos 111 15 UW Nikon and 150 Ikelite strobe.
Alfred,
I am sure it would have been a terrific feeling down there. The inclusion of the portion of that reef works. The colours that you see there is amazing. Haven't ventured into it. May be someday I would be able to do it. I am not sure how you swim and position yourself. Thanks for sharing.
