d. Another specialized technique involves the use of infrared film for
panoramics. Infrared may be used in any of the panoramic techniques listed, and
in many cases is shot along with panoramic emulsions to provide interpreters with
comparative views. Infrared has the advantage of detecting camouflage, since it
reproduces all living vegetation as white and all inanimate objects not covered
with special camouflage paint in shades of grey and black. It is also excellent
for penetrating haze, and therefore results in prints having more detail than
e. Filters are used in shooting virtually all panoramics, in order to
increase detail by cutting haze.
All filters which subtract blue from the
visible spectrum are used in this type photography, since haze is made up
primarily of blue radiations. No filter, of course, will penetrate fog, mist, or
f. Because of considerable reduction in scale, panoramics and overall
terrain photographs lack minute details. Therefore, photographers must, in many
cases, supplement panoramics and overall terrain images with large-scale,
detailed, close-up, pictorial records.
The number of photographs required and
in certain respects from what has already been covered.
Often, use of
a tripod will not be possible, and although hand-held photos will not
match as well as those shot from a stable support, any photos which get
back to friendly areas are better than nothing.
