Buzz Pioso's book Sight Unseen is informed by the progenitors of street photography—a genre with a focus that documents the everyday lives of people, primarily in a cosmopolitan milieu. The book's images reflect a keen observation of an often unseen and diverse humanity; people of all ages and ethnicities are his primary subjects. Pioso captures simple scenes such as people in conversation, hanging out, walking toward an unknown destination, waiting for or riding the Metro, and engaging with dogs. Some images are playful or humorous, while others are quiet and contemplative. Pioso instinctively understands how form and content combine to create a compelling street image, and the outcome is an homage to humankind that is both respectful and empathic.
