In moving camera
shots wider cels, backgrounds and drawings were used.
Panoramic (Pans) were often referred to as a 12 field
double pan (10.5" x 25") or a 16 field one and
a half pan (12.5" x 24"). A prime example of
where pan cels were used in numerous scenes in order to
accomodate the need for the wide screen process, are in
the films shot in cinemascope or technorama.
