Check out the documentary Finding Vivian Maier. Then head to the Arlington Museum of Art to see fifty of Vivian Maier's excellent black and white photographs. This woman worked as a nanny and also took photographs of ordinary people. "Her images represent an incredibly poignant glimpse into the lives of regular people going about the business of daily life." She lived in the North Shore area of Chicago. Over 150,000 plus negatives and rolls of undeveloped film were accidentally discovered, after she died in her 80s. This is fascinating and her perspective and eye for art was uncanny. Modest, unassuming, and immensely talented. This is street photography at its finest.
