Fitting the image to the screen
Fitting the image to the DMD
Without anamorphic lens
The projector can be configured by your installer to display a number of standard
image formats using the full height of the DMD. This means that the projected
screen height can be constant for all image formats, which is preferable for theatres
that employ only side-masking.
The exception to this is the 2.35:1 format, which can use the full width, but not the
full height of the DMD. Therefore any other image formats would have to be zoomed
down to maintain the same height.
With anamorphic lens
The projector can be configured by your installer to correctly display images that
have been compressed horizontally (or stretched vertically) by an anamorphic lens
when filmed. When the anamorphic lens is deployed, the image will be restored to
its correct aspect ratio.
In this configuration, the 2.35:1 format can use the full height of the DMD, and no
zooming will be necessary between this and other image formats.
