ail instances, whether it be in the camera, at the lab or on the
telecine. The Aaton XTR camera series, since its debut in 1984,
has been built for safe and trouble-free Super16 operation.
On the other hand, equipment that has not been designed with
Super16 in mind may cause rub, scratch or pressure marks within
the area once occupied by a second set
of
perfs. In order to be
sure that a certain device
is
compatible with Superl6, it
is
always
best to check with the manufacturer or the facility responsible for
the equipment.
2.2 Maintaining High Cuality
When Superl6 is to be used for
35
blow-up, for future HDTV
purposes, or for any other medium
of
greater resolution than
today's standard television, it is
of
uttnost importance to use the
appropriate equipment and develop practices that will ensure the
high quality
of
your images. Slight imperfections, which very
often pass undetected on an
NTSC or PAL screen, are greatly
magnified when viewed in a more demanding format.
The
XTRplus, with a registration tolerance
of
1/2000
of
the
image dimension both laterally and horizontally, delivers the
most stable and exact imaging
of
any 16mm camera available.
Your Super16 images, however, will only be as sharp
as
the lens-
es you use to capture those images. It
is
not enough to choose a
lens that merely covers the wider aspect
of
Super 16; just
as
important are the attributes
of
a lens such
as
sharpness, contrast
and zoom curve, which affect overall image quality.
See the list
ofrecommended lenses for Super 1 6 use, which follows.
The critical adjustment
of
camera and lens and their relationship
to one another insures that the lens
is
achieving its optimum
focus point at precisely the same distance
as
to where the film
plane lies. With the stringent requirements
of
Super16, it is rec-
ommended that camera flange focal distance (FFD) and lens back
focus be checked and precisely upheld by a qualified service
facility.
