Who among the following in 1856 has taken the first detailed photographs of the archaeological remains at Hampi ?

The ruins of Hampi (the capital of the Vijayanagara Empire) were first brought to light in 1800 by Colonel Colin Mackenzie, an engineer and antiquarian who prepared the first survey map of the site. However, the first detailed photographic record of the archaeological remains was created in 1856 by Alexander Greenlaw. These photographs are of immense historical value as they document the condition of the structures in the mid-19^th century before further deterioration occurred. Other notable figures in Hampi's archaeological history include J.F. Fleet, who began documenting inscriptions at the site in 1876, and John Marshall, who initiated formal conservation work in 1902.
