Asked what makes a good picture for him, Arnold Odermatt gave the laconic answer that became the subtitle of this first biographical publication about his pictures and his life. The book closes a gap in the literature on Arnold Odermatt, the Nidwalden policeman who, as a self-taught photographer in the early post-war period, began to document accidents, police duty, everyday life and his family with his 6x6 medium-format camera. The known sober-surrealist accident pictures relentlessly break through the central-Swiss idyll of family and professional life in the canton of Nidwalden.
