In the 1930s their style shifted toward the Neue Sachlichkeit, anti-expressionist objectivity then predominant in photography of Central Europe. The FiFo ("Internationale Ausstellung des Deutschen Werkbundes – Film und Foto") came to Vienna after being shown in Stuttgart and decisively influenced the Koppitz couple's artistic development. The Neues Sehen (New Vision) led them to a more factual and documentary oriented photography of themes from rustic life; ethnographic records of the peasant archetype, eulogised as the archaic essence of Germanic peoples, at first mystical and quasi-theosophical, but progressively more chauvinist and nationalistic under the Austrian chancellor dictatorship initiated by Engelbert Dollfuss of 1933. In 1936, the most comprehensive exhibition of Rudolf's work, a survey of 500 works of rustic subjects took place, entitled "Country and People", at the Museum of Art and Industry. Rudolf died that same year.
