Cinemascope or Anamorphic Format. he Widescreen Cinemascope format (commonly called the 2.35:1 aspect ratio) has become the established medium for movie theater or “Big Screen Cinema” presentations that may vary from 2.35 to 2.40 and even wider formats. The immersive properties are aesthetically pleasing and especially favored in dedicated home theater installations. This format is ideal for use with widescreen home theater projectors or 16:9 projectors using anamorphic lenses to create the full cinematic effect. Via Elite Screens.
