Since 2009, a historian has been traveling the globe for his visual research on major cities and megacities, driven by a search for a relevant image of the world in which we live: an urban world for more than half of humanity, with the trend going up. His shots are marked by an analytical observing eye, focused on space with all its signs, embedded in faceless structures that shape twenty-first century urban life. Neither architectural work in the narrow sense nor classic street coverage, he follows a tradition of urban observation inspired by conceptual artists working in a similar vein.
