The authors of these photographs are mostly unknown German Wehrmacht and SS soldiers who were stationed in Warsaw. They were able to freely move about the occupied city and take photographs using the most modern 35mm Leica and Contax photographic equipment of the time, brought from their homeland. They had easy access to supplies and photographic laboratories. Above all, though, the prohibition on taking photographs and even owning cameras that occupant authorities decreed for Poles, did not apply to them.
