Widescreen aspect ratio of approximately 2.39:1 (originally 2.35:1), historically achieved through anamorphic lens technology that squeezes a wider field of view onto standard 35mm film and de-squeezes during projection – creates the characteristic cinematic look with distinctive lens flares and bokeh.
What is Scope?
Scope refers to the widescreen format with a 2.39:1 aspect ratio, originally established by CinemaScope anamorphic technology. The term encompasses the aspect ratio and the characteristic look created by anamorphic lenses.

Today
Scope remains the preferred format for cinematically ambitious productions. Although digital cameras often achieve Scope through sensor cropping, anamorphic lenses deliver the authentic look that defines the format. The challenge on streaming platforms – a small effective image size due to letterboxing – does not diminish the format's artistic appeal.
