The first unseen colour photographs of France

 The following images show French cities, towns and attractions during the 1890s – and in colour. They were created using the Photochrom technique pioneered by Photoglob Zürich AG, which sees colour manually added to black-and-white negatives. The Swiss firm licensed the process to others, such as the Detroit Photographic Company in the US and the Photochrom Company of London.
