Ask almost any portrait photographer for the major influences on their craft or career and the name of Richard Avedon is likely to be mentioned.
Born is New York in 1923, Avedon studied photography before becoming an advertising photographer then opening his own studio in 1946. He worked for Vogue and Life magazine, specializing in fashion images but often breaking with tradition with both more natural and emotional images in outdoor locations, and his creative concepts.
He continued his fashion and celebrity work throughout his career with his subjects including The Beatles, Marilyn Monroe, Dwight Eisenhower, Christopher Reeve and Andy Warhol. His portraiture though also included many others, including civil rights activists, politicians, anti-war protesters and patients of mental institutions. In The American West has become widely seen as his most important collection of work, although some have also criticized it for being patronizing towards the subject material.
Avedon became known both for creating large prints of his work and also for his technique of using stark plain white studio backgrounds to simplify his images and direct all attention to his subjects.
Lessons to learn from Richard Avedon
Minimalism was certainly a tool that he used frequently, to remove distractions and have all attention focused on the subject in isolation from any surroundings.
Key to Avedon's work though was his interactions with his subjects, how he related to them to draw a response and find the image that he had in mind to create.
