[3] Intermittently between April 1930 and March 1933, Stern continued her studies with Peterhans at the Bauhaus photography workshop in Dessau, where she met the Argentinian photographer Horacio Coppola.

In 1933 the political climate of Nazi Germany led her to emigrate with her brother to England,[5] where Stern set up a new studio, soon to resume her collaboration there with Auerbach.

In the late 1940s and early 1950s, Stern created Los Sueños as illustrations for the woman's magazine Idilio and its column "El psicoanálisis te ayudará" (Psychoanalysis Will Help You).

[8] Stern's photomontages are surreal interpretations of the readers' dreams that often subtly pushed back on the traditional values and concepts in Idilio magazine by inserting feminist critique of Argentinian gender roles and the psychoanalytic project in her images.

Stern provided photographs for the magazine and served for a stint as a photography teacher in Resistencia at the National University of the Northeast in 1959 and continued to teach until 1985.
