After this she ran a photographic portrait studio in Munich until 1933, specializing increasingly in theatre photography. After her marriage to the Swiss painter Jules Fehr (1890–1971) in 1939 she went to Paris, where she opened the photography school Publi-Phot. During this period she became prominent through her experiments with solarization, double exposure, photomontage and the photogram. In the same year she founded the Ecole Fehr in Lausanne, training well-known photographers such as Jeanloup Sieff. After the incorporation of the school into the Ecole des Arts et Métiers in 1945 she withdrew from full-time teaching and worked as a freelance photographer in Territet, Switzerland.
