In this shot: The Hotel de Ville (Paris City Hall) was one of four focal points at Nuit Blanche 2011. The square and the streets surrounding it were swamped with contemporary art enthusiasts, tourists and young Parisians out for a good time. Across the street, at the BHV department store, every single window was lit up in blue and a strip of video screen looped a series of images in which words appeared and then transformed into a skyline, before collapsing and beginning the process again.
