I write from Casa de la Imagen, a cultural place sited in Logroño, Spain.
We has an impresive and unseen collection of 500 stereo negatives taken by an unknown french officer at WWI, who portrayed battles like Somme, Arras or Ypres, and people and weapons of all the Western Front's armies in high quality images. We had digitalized and restored the entire collection. You can see a small example here, in a special section inside the French Government official website to commemorate the Centenary: http://centenaire.org/fr/tresors-darchives/fonds-prives/archives/les-archives-photographiques-de-la-casa-de-la-imagen
Also, to reveal the 3D virtues of this exceptional images, Casa de la Imagen just made the video you can see here: https://vimeo.com/75787815 We had been experimenting with the gallery stereo mount, and we have improved a mirror system that allows big sized 3D copies can be seen to the naked eye, without annoying glasses, uneven videos or small and hard-to-see stereoscopes.
Our project is to make an exhibition and book showing the collection commemorating 1914-2014. If you are an organization or museum that can be interested, please feel free to contact us.
This is a basic information about the archive:
The collection was acquired at Tanger in 2003. It was contained in 10 wooden boxes, wherein each contains about 50 glass plates. In total, about 500 plates. All are unseen stereo negatives, made by a Verascope camera, if we believe in the advertising attached in the boxes. Each plate measures 4x10,5 cm, and each frame 4x4,5 cm. The conservation condition is variable, but mainly between good to excellent. The unknown French officer wrote notes between the stereo pairs. All the photos are dated, many are placed and a important portion has commentaries as "25/10/1917 Nettoyage du champs de batailles par les boches".
The photographer domains the stereo peculiarities, is technically superb and the photographic, military and historic information is very rich.
The author is anonymous (now we are investigating who it was, like detectives), but there is no doubt that is a French officer, maybe at the 54e Regiment d'Artillerie de Campagne. The photographer travels between Northern France and Belgium: Ypres, Amiens, Hooglede, Somme... The dates starts at 1916 and goes until the end of the war, even a familiar part of the collection after the war includes a visit to the post-war front. The officer was in close contact to the other allies armies, including a big amount of British and Commonwealth's themes photos, like soldiers and curious weapons.
Here you can see another video, this one larger and "flater": https://vimeo.com/70198950
Nowadays, we am working on a complete historic research on each image. The entire collection has been digitized by a full frame camera using a non-aggresive conversion method and restored, achieving high quality images for exhibition and publication purposes.
Also, if you want to help us in the author's research, you are completely welcome!
