'Naples, View from the North window of the third floor of No 233, Riviera di Chiaga', 22 May 1841. Daguerreotype by Alexander John Ellis (1814-1890). One of a series of topographical and architectural views which are among the earliest known photographs of Italy. Ellis wanted to use them as the basis of a series of engravings in a proposed publication called 'Italy Daguerreotyped'. The daguerreotype proces was one of two pioneering photographic proceses announced in 1839. Each image is a direct positive produced on sensitised metal plates in a long and complex procedure.
