He takes mainly pictures of cities, buildings and landscapes that require periods of exposure of up to 26 months, as in the case of his work on the Potsdamer Platz redevelopment in Berlin. Wesely was invited by MoMa to document its own construction and renovation project in 2001. His book Michael Wesely: Open Shutter was published as an outcome of that experience, edited by Sarah Hermanson Meiser. He has had numerous solo exhibitions around the world, such as The Epic View at Mies Van der Rohe Haus in Berlin (2014), An other pencil of nature at NordLB art gallery in Hannover (2013), mortos –vivos at the Centro Cultural in Sao Paulo (2012).
