Gjon Mili was an Albanese photographer, living in New York, who was born in 1904 and died in 1984, of a pneumonia. Known for his black and white long exposure pictures, he has worked a long time on artists portraits for magazine Life. On that time, the long exposure didn’t exist on the tools of cameras ; to get this effect, he used stroboscopic lights to illustrate the action and movements sequences. We can see dancers, Frida Kahlo, a Broadway dance of Marlon Brando and the walk of Hitchcock.
