Wide angle photography underwater is much more difficult than on dry land. I learned this lesson the hard way for sure on this trip. I took plenty of shots that I just didn't like at all. This one isn't perfect, but I kept it just the same.

Technical Data: Canon EOS 7D, Sigma 10-20mm f/4-5.6 EX DC HSM AF at 11mm, 1/160 sec at f/11. ISO 640. Ikelite Housing and Port with dual Ikelite DS 161 Strobes in eTTL mode. Raw conversion Adobe Camera Raw.

The first problem that jumps out of me is the strobe placement - I should have had one pointed at Anya so that both she and the anchor were equally illuminated and therefore avoiding the bluish color cast.

Next, ideally we should have waited a bit longer to let the backscatter particles to settle down after the other divers had moved on to get a clearer shot.

However, the proximity to the anchor lets it be a nice large foreground feature and gets plenty of light from the strobes to reproduce the vibrant colors of the sponges and corals.

It is definitely a challenge... one I definitely need more practice at to improve upon.
