It is as an early advocate of colour photography that Meyerowitz has had greatest influence, for he was instrumental in changing the attitude toward the use of colour from one of resistance to nearly universal acceptance. His subject matter altered from incidents on city streets shot with a small 35mm camera to the large format field photograph. Architecture, light and space, particularly at Cape Cod, acquired a new interest for him. After the destruction of the World Trade Center in New York, he was the only photographer granted unimpeded access to Ground Zero where he systematically documented the work of demolition and excavation, rescue and recovery. He has been awarded the title Photographer of the Year by the Friends of Photography, San Francisco. His work is in the collections of the Museum of Modern Art and the Metropolitan Museum of Art, and has been exhibited and published worldwide.
