The Wikipedia entry states that his earliest paintings were traditional, but a quick Web search didn't turn up any of those. What I did find were images of paintings he made following the famous 1913 New York Armory Show that introduced French avant-garde art to America. The exhibits influenced him to become a modernist painter, as did his association with Marcel Duchamp who was living in New York for about eight years starting in 1915. Man Ray also was strongly influenced by the Dada movement that began in Switzerland in 1916. At different times he considered himself a Dadaist and a Surrealist in photography as well as painting, though he supported himself mostly through commercial photography.
Below are examples of Man Ray's work starting with his early modernist paintings.
Here are two examples of his avant-garde photography, a field in which he was a genuine innovator.
Finally, an example of his commercial photography. Contrarian me, I much prefer it to his various modernist darkroom and paintbrush efforts.
