A Dufaycolor colour transparency of the view up The Mall towards Admiralty Arch from Buckingham Palace, London, taken by an unknown photographer in 1945. The Mall is lined with flags as soldiers and civilians get ready to celebrate VE Day and the end of World War Two in Europe. The Dufaycolor process was introduced as cine film in 1932 and as rollfilm for still photography in 1935. Based on Frenchman Louis Dufay's (1874-1936) Dioptichrome process of 1908, it was the last 'additive' colour process to be marketed. Dufaycolor consisted of a very fine, regular filter screen made up of red, green and blue lines printed on a film base. The process was popular with both amateur and professional photographers and survived until the 1950s.
