Roca Partida, Revillagigedos Islands

alex mustard swims around roca partida
This was the big rock we swam around a bunch of times while we waited for manta rays to arrive. It looks small here, but it feels pretty big when you are right next to the wall being pushed and pulled up and down by the surge. :)

Shot details: Canon EOS-1Ds Mark III, Canon 14mm/2.8 II lens, Seacam underwater housing, 2 x Ikelite DS-125 strobes, f7.1 @ 1/80 sec, ISO 320

I was using the wrong port extension, which explains why the image is so smeary around the edges.
