On the other hand, equipment that has not been designed with Su-
per16 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 Super16, it is always best to
check with the manufacturer or the facility responsible for the
equipment.
6.2.2 Maintaining High Quality
When Super16 is to be used for 35 blow-up, for future HDTV pur-
poses, or for any other medium of greater resolution than today's
standard television, it is of utmost 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 XTRprod, 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 lenses
you use to capture those images. It is not enough to choose a lens
that merely covers the wider aspect of Super16; just as important are
the attributes of a lens such as sharpness, contrast and zoom curve,
which affect overall image quality. See the list of recommended
lenses for Super16 use, in the Technical Specifications chapter.
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 recommended that
camera flange focal distance (FFD) and lens back focus be checked
and precisely upheld by a qualified service facility.
6.2.3 Ordering Film
When ordering raw stock from your distributor, make sure to speci-
fy Super16 or single perf film. In the US, where 16mm double perf
film is manufactured as standard, it is recommended to check stock
