Alexander Greenlaw, a British officer, is credited with taking the first detailed series of photographs of the archaeological remains at Hampi in 1856.
His albumen prints provide invaluable early visual documentation of the site before significant restoration or environmental changes occurred.
While Colin Mackenzie conducted the first comprehensive survey (producing maps and drawings) around 1800, Greenlaw’s work represents the dawn of photographic documentation at Hampi. John Marshall was a later Director-General of the ASI, involved in conservation in the early 20th century.
