The
film
mounted in the
slide
frame
is NOT
square
. For
the
entire
film
to be scanned, it is
necessary
to insert
the
slide
with the
narrow
side
of
the
film
, the
24
mm
side,
entering
first
into the
scanner
. This is shown in
Figure 4.4a.
The
entire
film
surface can NOT be scanned if the
wide
side
of the
film
, the
36
mm
side
is inserted
first
as
shown in Figure 4.4b. If the
film
is inserted as shown in
Figure 4.4b, the resulting scan
will
not
cover
the
entire
film surface. Known as
clipping
, this is shown in Figure
4.5.

Portrait
or
landscape is the
frequent
terminology
used
for
the non-
square
film
format. If the
image
on the
film
is
oriented so that the top of the
image
corresponds
to the
wide
side
of the
film
, the
orientation
is called
" landscape" and is
illustrated
in Fi
gure
4.6a.
Conversely, if the
image
on the
film
is oriented so that
the top of the
image
corresponds
to the
narrow
side
of
the
film
, the orientation is called "
portrait
" and is
illustrated in Figure 4.6b. This is identical to the
terminology
used in
preparing
an 8,5 x
11
inch page
for
text
processing
or
printing.

Since the scanner
requires
film
to be inserted
narrow
side
first
,
only
portrait
slides
are
actually scanned in a
top
correct
format. Landscape
or
iented
slides
will be
scanned
sideways
,
producing
a 90
degree
rotated
image
. This is corrected by the
software
after the scan
is completed. Since the rotation is
90
degrees
,
absolutely no
image
degradation
occurs.
