After his Bachelor in Arts he started his career as a freelance photographer in 1965 for Life. He first covered the Watts Riots in Los Angeles, where he documented many of the dramatic events, which earned him first accolades as a photographer.
Between 1966 and 1969 he was in Asia, where he particularly covered the Vietnam war. One of his pictures showed the commander of an M48 Patton looking through his lens. It was selected as World Press Photo of the Year and notably it was the first colour photograph to win the award.
