However, the advertising scandal gave her fresh impetus to start a new life. Collaborating with Conde Nast, she realized that she was much more interested in standing behind the camera herself, rather than acting as a model. In 1929 she moved to Paris with every possible letter of recommendation.
Lee set her sights on Man Ray, a Dadaist artist and distinguished photographer whose work she had long admired. At first Man Ray did not want to take her as his apprentice, assistant and lover. He was 17 years older. But Miller was not going to give up and thanks to her persistence, she and Man Ray had been inseparable for three years. Miller is said to have accidentally invented solarization – she was in the dark room but having felt a mouse or something running across her foot, she instinctively turned on the light. This technique became Man Ray's signature.
Lee became one of the outstanding photographers, often covering Man Ray on some projects, so that he was not distracted from more interesting shootings. However, she never put her own name. Meanwhile, she meets Pablo Picasso, with whom she maintained a lifelong friendship. Miller took more than 1,000 photographs of him for over the 36 years of their strong friendship.
Soon the relationship with Man Ray were becoming worse day by day. Lee got weary of Man Ray's outbursts of jealousy toward other Montparnasse artists and she was bored with his possessive attitudes. In 1932 she fled from him to New York. There she met the Egyptian-born businessman Aziz Eloui Bey, whom she married in 1934.
Man Ray was inconsolable, many noticed that he was on the verge of committing suicide. His artwork Object of Destruction – a metronome depicting Miller's eye – is the best depiction of his feelings after devastating breakup with Miller.
But Lee didn't care in the least. She was already with another man who took her to Egypt and where she created a huge number of photos, including the surreal “Portrait of Space”.
