The virtual presentation ECPAD: Première guerre mondiale is part of the ECPAD portal, the website of the Établissement de Communication et de Production Audiovisuelle de la Défense in Ivry-sur-Seine, the communication branch of the French defense ministry. At its portal ECPAD presents a selection of videos and photographs from its vast collection of First World War items, some 110,000 photographs (97,000 of them in the series SPA) and 2,000 films (series 14.18) which all have been digitized for the centenary of the Grande Guerre. One can consult the digitized items at the mediathèque in the old fortress Fort d’Ivry or order digitized images. ECPAD offers a very brief overview of its original audivisual collection created between 1915 and 1915, a general overview of materials from private collections concerning the Grande Guerre (PDF), and also succinct overviews of their First World War materials for a number of countries in Europe, Africa and Asia, and a set of fiches for each French département.
The online selection touches upon many themes in a wide variety of resources, among them for example coloured photographs (autochromes, 25 images in the selection, mainly to be found in the AUL series) and some 20,000 stereoscopic images (photographies stéréoscopiques, series D2 and D198), images of Russian soldiers in France, of prisoners of war, of the first American soldiers arriving in 1918, exercising army units, and much more. Only seven stereoscopic images are available online (animated versions).
There are only a few digital collections with French autochromes from the First World War. The main other collection is at the Mediathèque de l ‘Architecture et du Patrimoine, discussed also here. Parts of both collections appear also elsewhere. At Arago-Le Portail de la Photographie you find more about several early techniques for colour photographs.
