2.39 is in fact what they generally are referring to (unless discussing films using the process between 19), which is itself usually rounded up to 2.40. A 1.85 is very close to 16:9, the bog-standard televisual aspect ratio settled on in the 1980s as a good compromise between TV and wide-screen cinematic dimensions. Īnamorphic prints are still often called Scope or 2.35 by projectionists, cinematographers, and others working in the field, if only by force of habit. At these modern dimensions (0.825 in by 0.690 in-1.19:1), the unsqueezed ratio remains at 2.39:1. The most recent revision, from August 1993 (SMPTE 195-1993), slightly altered the dimensions so as to standardize a common aperture width (0.825 in) for all formats, anamorphic and flat. This new aperture size, 0.838 in by 0.700 in, (1.19:1) makes for an unsqueezed ratio of 2.39:1 (more commonly referred to as 2.40:1). A new definition was created in October 1970 (PH22.106-1971) which made the vertical dimension slightly smaller in order to make splices less noticeable (as anamorphic prints use more of the negative frame area than any other modern format) when projected. The earliest films were presented in a 4:3 ratio, and until the advent of widescreen HDTV, 4:3 was the normal ratio. The aspect ratio for this aperture, after a 2x unsqueeze, rounds to 2.35:1. There have been many different aspect ratios throughout the history of film and television, but today, four ratios are common, with a few classic ratios making a comeback. The first SMPTE definition for anamorphic projection with an optical sound track down the side (PH22.106-1957), made in December 1957, standardized the aperture to 0.839 in by 0.715 in (1.17:1). Result: Resolution needed for indistinguishable pixels in 16:9 images. To complicate matters, the SMPTE standards for the format have varied over time to further complicate things, pre-1957 prints took up the optical soundtrack space of the print (instead having magnetic sound on the sides), which made for a 2.55:1 ratio. Visual Acuity in degrees (Vaq) 1 /60 degree or arc minutes.
However, due to a difference in the camera gate aperture and projection mask sizes for anamorphic films, the image dimensions used for anamorphic film vary from flat (spherical) counterparts.

Since the anamorphic lenses in virtually all 35 mm anamorphic systems provide a 2:1 squeeze one would logically conclude that a 1.37:1 full academy gate would lead to a 2.74:1 aspect ratio if used with anamorphic lenses. Note: Many say 2.39:1, 2.40:1 (two-four-oh) or 2.35:1, but nowadays these typically all refer to the same 2.39:1 aspect ratio. Even buses pass us on a set ratio.One common misconception about the anamorphic format concerns the actual number of the aspect ratio itself. Ratios are everywhere in our lives, from the amount of vergetables and fruit we eat per day to the split of calcories we consume in general.
