Image caption,A famous early European commercial photographer, Samuel Bourne, arrived in India in 1836. Initially partnering with William Howard, Bourne set up the Howard & Bourne studio in Shimla. They were joined by Charles Shepherd, but after Howard left, the studio dropped his name to become Bourne & Shepherd. India's Tasveer gallery is holding an exhibition of rare Bourne & Shepherd photography this month. This is an 1860 picture of a group of Affreedies, an Afghan tribe from the Khyber Pass.
