Walter Frentz (1907–2004) began his career as a cinematographer and photographer in the 1920s, creating kayak films and photographs in the style of the New Vision. Starting in 1933, through Albert Speer’s recommendation, he worked as a cinematographer for Leni Riefenstahl and created some of the most famous scenes in “Triumph of the Will” and "Olympia*. 

In 1940, he became the resident cinematographer at Hitler’s headquarters. In this role, he not only filmed all official events but also took photographs incessantly in color. In addition to his work at headquarters, he documented the construction of the Atlantic Wall and armaments projects such as the V2 rockets from 1942 to 1944, as well as the murderous slave labor forced upon prisoners at the Dora-Mittelbau concentration camp for their production. In the spring of 1945, he finally created entire series of images depicting destroyed German cities. 

The book clarifies the circumstances surrounding the creation of the images, examines their propagandistic aspects, and traces the career of Walter Frentz, which he was able to continue unhindered as a cultural filmmaker after 1945.
