Anyone entranced by the Autochrome photographs in the current BBC4 series The Edwardians in Colour: The Wonderful World of Albert Kahn will want to know about an upcoming exhibition at the National Media Museum in Bradford, celebrating the centenary of the Autochrome. It’s not moving pictures, of course, but the Autochrome – the most beautiful of all colour photography systems (it’s all down to the potato starch they used…) – was invented by Auguste and Louis Lumière, inventors of the Cinématographe, and so it gets honourable mention here. The exhibition is called The Dawn of Colour, and runs 25 May-23 September 2007. More news once it’s started.
