Outgoing tide near Worthing, UK 2012.
The red float and snorkler you see in the shallows is a guy fishing with a harpoon, he caught 6 good sized mackerel which they later cooked on a beach BBQ.
Shot with a Canon 40D, battery grip & Hahnel Giga-T Pro timer with a tripod sat on solid rock.
1394 RAW images totalling 17GB, taken at 6 second intervals trying to balance the peoples movements against the slower moving tide. There were 5 exposure (ISO) changes as the light fell.
