 He was sent for convalescence to a military hospital in Budapest, but was later transferred to Esztergom, where he continued to take photographs. These included a self-portrait for a competition in the magazine Borsszem Jankó. His most famous piece of this period was "Underwater Swimmer, Esztergom, 1917", the only surviving work of a series of a swimmer whose image is distorted by the water. Kertész explored the subject more thoroughly in his series of "Distortions" photographs during the early 1930s.
