Between 1922 and 1925 he lived in Paris, where he sold prints for 25 francs in order to make a living. During this time he began his collaboration with the Frankfurter Illustrierte, the Berliner Illustrinte, the Nationale de Fiorenza, Sourire, Uhu and Times. In Paris he began his seriesDistortions.

He attempted to bring over his negatives from Paris, but more than half were lost in transit. From 1949 to 1962 he worked continuously for Conde Nast.
After a serious disease, Kertész decided to cancel all his contracts and work exclusively as a freelance photographer.
