"Cities are made of details that no one notices. Not because they are hidden — but because we have stopped looking. A shadow that divides a wall into two perfect halves. A grate that turns light into a grid. The specific way winter light strikes an iron railing at four in the afternoon. I have photographed the same cities for thirty years and I still find new things to look at. Paris and New York are not places I have seen. They are places I am still seeing."
