This table will provide the reader with a visual comparison of the projectable area of various motion picture systems. Why is this important? If you must ask then we'll tell you. The greater the amount of film area that can be projected onto a screen, the greater the sharpness and detail, not to mention the brightness. Bear in mind that these drawings represent the areas of the projection print, and not the photographic negative. It should be fairly obvious why Cinerama, despite panel match lines that some viewers couldn't seem to ignore, was still the king of wide screen systems from a picture quality standpoint.
