"documenta 12" reasons on a visual level. Artists are photographing the exhibition for a book of images: the artworks and the spaces, the spaces between the artworks, and the beautiful Kassel setting. This photo volume presents the art projects that were produced especially for documenta 12, as seen by twelve photographers commissioned for this book project. About documenta: documenta is regarded as the most important exhibition of contemporary art, drawing attention from all over the world. This international exhibition, often called the Hundred Day Museum became an unparalleled success. The number of visitors has continually risen. More than 650 thousand visitors came to documenta 11. Under continually changing directorship, and in the equally leisurely and inexorable rhythm of five years, documenta has advanced to become an authoritative worldwide seismograph of contemporary art. At documenta, it becomes manifest whether art is succeeding in grasping the world in images and whether these images have validity for its public.
