The book to the Triennale der Photographie Hamburg 2018. Since 1999 this large international festival (with around 80 exhibitions and over 300 artists) gives every three years an overview of contemporary developments in artistic and documentary photography. The large Hamburg exhibition institutions (Kunsthalle, Museum für Kunst & Gewerbe, Deichtorhallen and others) take part in the Triennale with their own exhibitions. The subtitle of the book is also its theme.
