Note that aspect ratio refers here to the projected image. There are various ways of producing a widescreen image of any given proportion. Complicating the discussion is the fact that the common names for aspect ratios actually refer to the companies that patented a specific camera or projection system (and Panavision, for example, has a line of cameras that can be adapted for many ratios).

Cinemascope required anamorphic? lenses that put a distorted image on film stock of the ordinary ratio and anamorphic projection lenses to unsqueeze the image and spread it over the wide screen. But competing companies produced widescreen images in the same ratio merely by masking part of the frames taken by ordinary cameras--sometimes using a "hard matte" in the camera itself, sometimes by specifying projector mattes.

A low-budget movie called SECRET FILE: HOLLYWOOD, often ridiculed as a collection of bloopers, is actually an example of a film that is always projected wrong. All the lights and microphone booms visible above the actors should be concealed by a projection matte, creating an image that would fill a wide screen for little money.

There are also widescreen processes that use larger film frames: 65mm, 70mm. These can increase both the height and the width of the image.
