Representative of the inter-war avant-garde, Krull established herself as a figure of the Nouvelle Vision in France with her 1928 portfolio Métal and reporting for the review VU (with André Kertész and Eli Lotar). She is known for her portraits of Jean Cocteau and André Malraux, Autoportrait à l’Ikarette, and her shots of metallic architecture. In World War II, she worked for the Free French Forces in Africa. After the war, she gradually distanced herself from photography to manage Bangkok’s Oriental Hotel and live in an Indian Ashram.
