Indian worker, Sandip Ghaosh adjusts a 174-year old Wet Plate Camera manufactured by W. Watson & Son, London inside the century-old Bourne and Shepherd studio on World Photography Day in Kolkata on August 19, 2014. Bourne and Shepherd, established in 1863, is the oldest photographic studio still in operation and one of the oldest established photographic businesses in the world. At its peak it was the most successful commercial firm in 19th-and early 20th-century India, with agencies all over India and outlets in London and Paris, and also ran a mail order service.
