Jim Schaefer - Snorkelers and Scuba Divers

Some of the most mind-blowing scenes seen from underwater are those looking at the surface from below. It has similarities with viewing the surface from above - alternations between reflective areas where the water is a mirror and opaque areas where we look down into the water. But from underneath we look out into the atmosphere and what's below is reflected. So it's kind of the inverse. Water crashing on rocks sends waves of reflective bubbles downward and snorkelers appear as eery, headless creatures.
