Along with Heinrich Hoffmann, the cameraman and photographer Walter Frentz was one of the most important propaganda photographers during the Third Reich. In the 1930s-1940s he worked as a cameraman for Leni Riefenstahl. He was one of the few photographers allowed in Hitler's closer circle and the more private photos he made of Hitler were never intended for publication. Frentz took part in the early experiments with color paper in Leverkusen.
