I recently had the chance to dive with the thresher sharks in Malapascua. I had been there before, and gotten good pictures of the sharks. This time I was diving with my new Pelagian CCR - it was a blast. Without bubbles I could have taken macro shots of the parasites on the shark skin.
Lucky you, we dived with Siren in Jan this year, saw the thrashers but not close enough to focus D7000. Had great whale shark encounter South end of Cebu. New to this website, not sure how to post pics, but you can see them on my website. www.critter-hunter.smugmug.com
The second shot is beautiful !!
I envy you... !! CCR is definitely the best way to get as close as possible from sharks !!
