I went over to the Marin coast on a day with a high surf warning. There was wind, too. I captured this breaking wave directly into the sun using a fast shutter speed (1/1250 of a second) to stop the motion. The sun made the wave translucent and helped increase the contrast in the patterns on the water.
Exposure data: Nikon D300, 400mm, circular polarizer, 1/1250 of a second at f/40 and ISO 200, tripod mounted.
