	2.35 source material in its
	native aspect ratio.
	With a 16:9 screen and a
	non-CineWide projector
	(no anamorphic lens), the
	upper and lower portions
	of the screen are masked,
	but the geometry of the
	active image area is
	unchanged.
Cinema		2.35:1
	With a 2.35:1 screen and a
	CineWide-equipped
	projector, the video
	processor scales the 2.35:1
	image so that the active
	image area fills the 16:9
	chip surface, eliminating
	the black bars. The
	secondary, anamorphic
	lens then restores the
	proper geometry to the
	2.35:1 image.
	A 16:9 image is scaled
	NON-linearly (more on the
	sides than in the center)
Intelli-	to fit a 2.35:1 screen.	16:9
Wide 2.35
	IntelliWide 2.35 is
	available only on the
	Vision 15ET/CineWide.
