Another shot from my dive trip to Hin Daeng in southern Thailand with my friends Richard and Heather. On one of the dives I was tired and chose not to dive. As the divers were returning to the boat, I was snapping photos like crazy. I have no idea how I got this picture. I did not do any digital retouching on it; what you see here is what I got. Somehow the boat was moving, and I was moving, and the camera was moving, and Heather was moving in such a way that Heather’s face was perfectly still in the center, and everything else was swirling around the edges.
