4.2.2 Theatre Variables: Masking
In order to present either type of feature on a single screen, a theatre typically uses masking to conceal any
unused edge(s) of the screen. These movable panels or curtains are most commonly installed along the top
edge of the screen, changing the height of the screen but not its width. The screen shown in
Figure 4-4
also has
a bottom mask.
• Add masks for scope
• Open masks for flat
Alternatively, masks may be installed at each side of the screen in order to change the width of the screen but
not its height. (
Figure 4-5
)
• Add masks 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.
Refer to
Table 4.2
for a summary of the basic factors affecting cinema displays in a variety of theatres.
