Breaking Wave, photo by Harold Davis. View this image larger.

Walking along the Marin Headlands cliffs between Rodeo Beach and Tennessee Beach, I was struck by the brightness of the breaking waves in the sunset light against the darkness of the shore in shadow.

Depth of field was not an issue. I spot metered for the brightness of the waves, made sure that a shutter speed fast enough to stop the motion of the wave was selected, and allowed the camera to choose the aperture.
