His black-and-white photographs have an elegiac quality that sensitively capture the misty, grey climes of Iceland, the rarely-noticed details of China's bleak and dreary urbanscape, and the grand colonial buildings of Calcutta that had seen better days. A zoologist by training, this self-taught photographer mostly uses a cumbersome studio camera or else an ancient Rolliflex even in the busiest streets, and yet human beings are rarely sighted in his works. So, his photographs never fail to surprise. He has held critically-acclaimed exhibitions in Paris, Arles, London, Beijing, Delhi, Mumbai, and Calcutta.
