It was shot above the ringroad toward Saint Luce in Nantes (France) at 9am. I wanted to show the way vehicles move, to observe the flow and rhythm of traffic, to look at the mobility challenge faced in day-to-day life. This photo is a composite of 15 pictures taken at different exposures ranging from 1/125s to 20 seconds exposures at f11 using a 35mm lens on a tripod and a 9 stop light loss filter.
