Projector Variables: Using a Wide Converter Lens

The optional Wide Converter Lens acts similar to a zoom lens. It magnifies a "flat" image format of 1.85:1 to a
"scope" image of 2.39:1, while maintaining the full resolution of the source material.

Theatre Variables: Masking

In order to present either type of feature on a single screen, a
theatre typically uses masking to conceal any unused edges(s) of
the screen. These movable flat black panels, or black curtains, are
most commonly installed along the top edge of the screen
changing the height of the screen but not its width.
Top Masking
• Add top masking for "scope"
• Raise top masking for "flat"
Side Masking
Alternatively, curtains (masks) may be installed at each side of the
screen in order to change the width of the screen but not its height.
• Bring in masking from sides for "flat"
• Open masks for "scope"
In some cases, a theatre has both side and top/bottom masking installed.
This arrangement is the most flexible of all.
