The First World War was the first major conflict where photography played an important role. Germany recognised its potential and used photographs for propaganda from 1914. The images were used to influence the public opinion in neutral countries. France realized that it could not stay behind and decided to set up its own photography unit to oppose German propaganda.
Most French stereoviews with images of the First World War contain a short description which is printed on the slide. In best case, it describes the place, subject and a year. However, most descriptions are brief and sometimes even incorrect. This makes it difficult to find out more about the story behind the image.
