Instead of using traditional photography techniques, the American photographer Jay Wolke relied on a small portable high-resolution scanner to explore varied surfaces and plots, which he then assembled and post-produced in a kaleidoscopic synthesis. By inverting the relationship between micro and macro, the author conveyed his investigation of the small elements on an innovative and monumental format, which translated small details into large and long vertical banners. Wolke used a combinatorial system to hold together the various souls of the Arno River, ranging from postcards for sale on noted tourist bridges to lichens on the cement of the river banks, icons linked to the imagery and the history of the river, plants and flowers growing spontaneously along the banks. Five key words were chosen by the author to pinpoint the various subjects displayed in the five works: Arno flow, Arno bridge, Arno love, Arno flood, Arno restore (2016).
