In a Chicago Magazine article on Vivien Maier, Colin Westerbeck, former curator of photography at Chicago's Art Institute, co-author of Bystander, and an expert on SP is quoted thusly: “She [Meier] worked the streets in a savvy way,” he says. “But when you consider the level of street photography happening in Chicago in the fifties and sixties, she doesn’t stand out.” Westerbeck explains that Maier’s work lacks the level of irony and wit of some of her Chicago contemporaries, such as Harry Callahan or Yasuhiro Ishimoto, and unlike them, she herself is often a participant in the shot. The greatest artists, Westerbeck says, know how to create a distance from their subjects." Are irony and wit essential? Optional? Unnecessary? The part about distance and participation was also interesting. Are you a participant, do you keep your distance (this is not a physical distance, btw more regarding interaction)? Or inject yourself into your photos?
