The pictures of the Wien | Berlin gallery are double exposures – for each image one exposure was taken by Natalie Opocensky in Vienna, the other one taken was by Thorsten Strasas in Berlin. A first exhibition of the Wien | Berlin project took place during the European Month of Photography in Vienna in November 2012.
