PANORAMAS

These two exposures together cover a horizontal
angle of 92° without turning the
camera, 8° 30'
more
than the range of a 20mm wideangle lens,
and
with
the added advantage of larger image size. The table
below gives a comparison of the angles of various
wideangle lenses and the PC-Nikkor panorama range.
In making a vertical panorama, a 79° vertical angle
can be covered using the extreme rise and fall shifts,
with the camera still in the horizontal position. The
overlapping area is least when two pictures are
matched vertically.
Caution: Extreme care is necessary when taking panoramic
shots to avoid camera
movement,
since even a slight movement
between exposures will result in some distortion and photo·
graphs will not join exactly. For best results mount the camera
on a tripod.

When making enlargements,
be sure
that the negative is absolutely parallel
to the easel to prevent
distortions.
All of the focusing adjustments on
the enlarger should be maintained
constant from one exposure to the
next. When the prints are removed
from the washer, insert them in a
rotary dryer facing the same direction
.
