Anamorphic Attachments

A recent trend in cinematography is to provide the audience with a wide field of view. This, of course, may be accomplished by using a wider film (70 mm rather than 35 mm). However, it is more economical and certainly more convenient to be able to photograph and project using 35-mm film. Chretien (1931) was perhaps the first to devise a process using anamorphic lenses.
