Colour photography was already well advanced in the late 19th century, but was prohibitively expensive. Around 1890 the Swiss company Orell Füssli developed the photochromy: the manual colouring of black and white negatives and printing by means of lithography stones. Photoshopping avant la lettre, a technique that became well known by the American Detroit Photographic Company, which produced a large number of photochromic postcards around 1900. From the first colour photos of France, we made a selection of 22 beautiful photochromic prints of cities and tourist attractions, from Calais to Marseille.
