We didn’t plan on snorkeling so late in the day in St. Lucia and were surprised when we looked up to see the sun was dipping below the horizon. My camera was a waterproof Canon Powershot D10, which we used almost exclusively for underwater pictures. At the surface, I turned the flash on to counter the backlight from the sunset, tried to set up the angle as best I could while treading water…and just got lucky. I used auto contrast and color from Picasa, but that did not change much at all.
