He initially set up in partnership with an already established Calcutta photographer, William Howard. They moved up to Simla, where they established a new studio ‘Howard & Bourne’, to be joined in 1864 by Charles Shepherd, to form ‘Howard, Bourne & Shepherd’. By 1866, after the departure of Howard, it became ‘Bourne & Shepherd’, which became the premier photographic studio in India, and until it closed in June 2016 was perhaps the world’s oldest photographic business. Charles Shepherd evidently remained in Simla, to carry out the commercial and portrait studio work, and to supervise the printing and marketing of Bourne’s landscape and architectural studies, whilst Bourne was away travelling around the sub-continent.
