High Quality Content by WIKIPEDIA articles! Pan and scan is a method of adjusting widescreen film images so that they can be shown within the proportions of a standard definition 4:3 aspect ratio television screen, often cropping off the sides of the original widescreen image to focus on the composition`s most important aspects. Some film directors and film enthusiasts disapprove of pan and scan cropping, because it can remove up to 45% (on 2.35:1 films) of the original image, changing the director or cinematographer`s original vision and intentions. The vertical equivalent is known as "tilt and scan" or "reverse pan and scan".
