This picture was taken at one of the open beach's near the Allegro Hotel at Cozumel. Supposedly out in the direction of the sun, about 100 meters, is some very good corral reefs for snorkeling/diving. I took this photo with my Canon 7d. I did very little to it in Apple's Aperture (not that I'd now how to do much more then auto-level-cleanup, it's a learning process) but I don' think this frame even required that. This is almost identical to how the view looked to our eyes that evening. I am quite happy with how this frame capture turned out.
