2. Large screen projection

With the advent of the cinematograph, Frenchman Louis Lumière and American Thomas Alvas Edison adopted a 35mm film format for shooting, projection and printing, with virtually identical characteristics (see ). However, this format, which spread at the end of the 19th century (and became the standard for traditional cinema), was not the only one developed and used. Inventors and filmmakers experimented with wide-format film. Particular attention was paid to intensifying the psychological impact of cinematographic representation on the public — through improved image quality (due to increased film width) —, or the scientific impact of recording a specific scene (notably in the context of observing human and animal locomotion).
