The digital collection Autochromes de la guerre 1914-1918 has been created as a section of the French portal Médiathèque de l’Architecture et du Patrimoine. Among image collections concerning the First World War this is one of the most renown. The photographs were taken in France, Tunisia and Greece. The collection illustrates also the role and presence of African soldiers. Apart from the colour photographs the portal has a general section on the First World War, the Archives photographiques: Guerre de 14-18. Both collections can only be viewed in French. In the online database Base Mémoire for the images in the Archives photographiques you can use an advanced search mode with multiple fields, but also a free text search (recherche libre).
The images in this collection appear also elsewhere, for example at the portal The Great War and at World War I Color Photos, with comments in English which sometimes give more information than the original French comments. The collection appeared also at the digital portal Gallica of the Bibliothèque nationale de France, but it has been removed. World War I Color Photos has arranged the images according to the sets at Gallica. The main other digital collection with French autochromes from the Grande Guerre is available at the website of the ECPAD, discussed here, too.
