he new Ciné-Kodak Eight-20 camera took a 25-foot (7.6 meter) roll of 16mm wide film with twice the usual number of perforations. The film was run once through the camera, exposing quater-size images down one half of the width of the film. The film was then reloaded and run back onto the original spool, taking a second set of pictures on the other half of the film. After processing, the reversal developed film was slit down the middle to make two lengths of 8mm wide film, which were joined together to make a 50-foot (15.2 meter) length which would last for four minutes in the projector. Despite the very small frame size, the image quality was very good, certainly adequate for most uses, achieved through the use of specially developed high resolution emulsions. In an effort to reduce even further the already small size of the camera, in September 1935 Bell & Howell announced the Filmo Straight Eight camera, in which a 50-foot (15.2 meter) roll of 8mm wide film was run once through the camera. The Universal Camera Company followed with the Univex Straight 8 camera using the same film loading method. Other single-run 8mm cameras appeared in the following years, but the system had its drawbacks and it never achieved the wide popularity of the "double-run" 8mm system.
