According to the BBC the first exhibition in the UK featuring salt and print photographs – the earliest form of paper photography – opened at Tate Britain on 24 February.
In the 1840s and 50s, the salt-print technique, which was invented in Britain, introduced a revolutionary new way of creating photographs on paper.
The 90 photographs are among the few fragile salt prints that survive, and are seldom shown in public. Among them Nelson’s Column Under Construction, Trafalgar Square, 1844, by William Henry Fox Talbot.
