Nicholas Studios in Madras and Ootacamund was one of the premiere South Indian photography firms starting in the 1850s. Their long history and that of A.T.W. Penn is nicely covered in the book by Christopher Penn, The Nicholas Brothers and A.T.W. Penn Photographers of South India 1855-1895, one of the first books to investigate the much less-researched field of early photography in the south.
