When Professor Rolf Nobel of GAF (Galerie für Fotografie in Hannover) asked me if I would like to be a part of their exhibition "Flussgeschichten", I did not hesitate for a second. Alongside some great colleagues, Rolf and his team put together a wonderful showcase of photographs about all kinds of rivers. More than 2000 visitors saw the exhibition. Thanks GAF for the opportunity to be a part of this.
