When Kirchner began working with photography at the beginning of the 20th century, he could already look back on a generation of photographically trained painters who were able to integrate photographic manipulation techniques into their paintings. As a classically trained architect and avant-garde artist, it was simply impossible for Kirchner to use his photography as a purely technical means of reproduction independent of art production. This exhibition now looks at this unique interweaving of painting and photography in the painter's oeuvre.
