In addition, he started photography - his mother gave him the first camera. Although she did not share interests of her son, but she still believed that the young man would be able to combine the work of a rabbi and painting and photography. Therefore, she in big secret from the family, presented Saul his first camera. Meanwhile father insisted that the son should abandon his passion for art. Photography, in his opinion, was destiny of losers with a dubious lifestyle. And when a note about Saul’s second exhibition was published in a local Jewish newspaper, his father burst into tears of shame. That was the last straw. The young man packed his suitcase and left the house in the middle of the night. For the rest of their lives, the brothers considered the photographer as "freak", and the father did not forgive his son.
Reaching New York, Saul quickly found new friends there. Friendship with Eugene Smith, who was involved in photography, and the artist Richard Pusett-Dart, who created canvases in the style of abstract art, had a special influence on the genius of street photography.
It was 1949. That time everyone was photographing on black and white film. Saul was capturing quite unusual images. He was not only catching new angles, his collection has works that capture images through misted glass. Saul was photographing and making artistic pictures in fog and snow, heavy rain. He did not seek to convey an accurate picture of what was happening. Leiter preferred abstract works, which give rise to doubts about what you see in front of you.
In 1953, some works of the photographer were presented at an exhibition in one of the New York museums, where they were noticed by employees of Vogue, Esquire and Harper’s Bazaar magazines. They offered Saul job, which lasted 20 years, but the photographer did not achieve big success in fashion.
