TIME LightBox talks to Mary Ellen Mark as part of our series “The Photo That Made Me”, in which photographers tell us about the one photograph they made that they believe jump-started their career, garnered them international attention, or simply reflected their early interest in photography. In 1965, I was in Trabzon in eastern Turkey on a Fulbright scholarship. I would get up every morning and walk around the streets and look for photographs. One day, I came across this beautiful young girl, Emine. She was wearing a very babyish dress and a bow in her hair. I photographed her, and she invited me to come to her home.
