EARLY EPIDEMIC IMAGE
Paul Marès Ox Cart, Brittany, c.1857.
Apparently a picturesque scene of bucolic tranquillity, this photography also reveals two white crosses painted on the cottage wall, a warning that the place was afflicted by the outbreak of some deadly disease.
British photographer, William Henry Fox Talbot, invented the salt print, the earliest form of photographic negative. Salt and Silver is the first exhibition in Britain devoted to salter and paper prints, and includes around a hundred prints from several photographers, made between 1830 and 1860.
Where: Tate Britain. Until 7 June.
