For more than a decade, Michael Wesely has been inventing and refining techniques for making photographs with unusually long exposures-some as long as three years. In 1997 he began using this unique approach to photography to explore major urban construction projects, such as the rebuilding of Potsdamer Platz in Berlin. Buildings that are demolished or constructed over the course of Wesely’s long exposures often appear ghostlike, evoking simultaneously a vanishing and emerging presence.
