Iceberg arch collapse in Antarctica

When I was on the Sea Shepherd boat in Antarctica during 2009/2010, I captured an unusual sequence of images: a sequence of an iceberg arch collapsing. I literally raised my camera to my eye (Canon 1D Mark II w/70-200/2.8L lens), and the arch collapsed. I mashed the shutter button down and captured 20 frames—in bursts. I shot in bursts because I was afraid that the buffer wouldn’t hold. Later, I pulled the frames into Motion and created this video.
