A Sinking Feeling

In anticipation of my upcoming dive trip to the Keys, I found a dive photography blog that, http://www.uwphotographyguide.com/ , that has a few articles that highlight techniques to make underwater shooting much more exciting.



The article I found gave tips to get sunburst shots underwater, such as using a low ISO, a fast shutter speed and a smaller aperture.
