Raghubir Singh (1942-1999) is considered by many to have been one of the twentieth century's finest colour documentary photographers. Born in Rajasthan, his work is in the permanent collections of a number of major museums, including The Art Institute of Chicago, the Metropolitan Museum of Art and The Museum of Modern Art in New York, and the Tokyo Metropolitan Museum of Photography. His many publications include books on Kerala, Rasjasthan, Bombay and the Ganges. River of Colour, also published by Phaidon, is the first ever published retrospective of his work.
