Widescreen

A widescreen image is a film image with a greater aspect ratio than the ordinary 35 millimeter frame. The rationale is that, since the human eye has a field of view that extends further to the sides than it does above or below, a widescreen image makes more effective use of the field of view, thereby producing a more immersive viewing experience.

The aspect ratio of a standard 35 millimeter frame is around 1.37:1, although cinematographers may use only the part of the frame which will be visible on a television screen (which is 1.33:1 for standard television). Viewfinders are typically inscribed with a number of frame guides, for various ratios.
