Construction of the New York Subway, Grant W. Pullis (attributed to), 1909

cyanotype, h 190mm × w 236mm More details

Photographs can sometimes serve a purely practical purpose, such as documenting construction work. In the years around 1910, Pierre and Grant Pullis (father and son?) took hundreds of photographs of the construction of the New York subway. They used the extremely simple cyanotype technique, which yielded blue coloured prints of great and unintentional beauty.
