Fig. 4: The wreck of the SS Numidia which sank in 1901. What you don't see on that picture: Here on that corner the current was extremly strong. The bubbles did not go up, but stayed in a whirl in position. I had trouble swimming to the current shadow and almost threw away my big bulky camera. Also not good with a slight cold and decompression problems in my forehead. — Nikon D200, Nikkor AF-S DX 10.5 Fisheye, Little Brother Island, Red Sea, Egypt, 13 November 2011 Nikon D200; Δt=1/250 s; f=10.5 mm; f/5.6; ISO 200; 13 November 2011 09:50:04
