A 10 minute long exposure of the bridge that connects the Île de Ré with La Rochelle in France.
It was taken at dusk and the dying light changed dramatically during those 10 minutes.
This is the most difficult photograph that I've ever taken as it took me a full week of trying to judge the correct exposure to get this single image.
