Silent Aperture ist die historische Basis für moderne Filmformate. Das Verständnis der Apertur-Geschichte erklärt, warum Super 35 heute so beliebt ist – es nutzt praktisch die gleiche Fläche wie das Original-Stummfilmformat.
The original full-frame 35mm film format used during the silent film era before the introduction of optical sound tracks – measures approximately 18x24mm, utilizing nearly the entire width of the film strip, later reduced to Academy Aperture when space was needed for sound.
What is Silent Aperture?
Silent Aperture refers to the original 35mm film format of the silent film era (approx. 1895-1930). It utilizes almost the entire width of the film strip between the perforations, offering the maximum image area of the 35mm format.
