(4) Kodak Ektachrome. A transparency (slide) film available in a variety
of film speeds from 100 to 3200.
(5) Kodak Vericolor or Kodacolor. Color negative materials for producing
color prints. Available in ASA/ISOs from 100 to 1000.
b. Film processing is an important part of the mission planning.
Once a
mission is flown, you don't want the film ruined during processing! If special
or speed processing is required, be sure arrangements are made with the photo
facility.
Any special processing requirements should be noted in the Special
Instruction section of the DA Form 3903.
Learning Event 2:
DESCRIBE THE TECHNIQUES USED IN AERIAL DOCUMENTATION PHOTOGRAPHY
1.
Techniques.
a. Grid coordinates are required pinpointing the location of targets, and
the photographer should have a working knowledge of them should it prove
necessary to refer to coordinates while in the air.
They provide a quick,
precise means of establishing targets, and eliminate misunderstanding between
pilot and photographer as to objectives.
b. After planning the flight with the pilot, the photographer exercises his
knowledge of techniques.
The pilot's responsibilities lie in the realm of
getting the cameraman over the target area at the desired height and/or angle.
The rest is up to you.
You may talk to the pilot through an intercom or by
prearranged hand signals to make additional passes over the target, go higher or
lower, bank, etc.
2.
Types of Photos.
a. Once over the target area, exactly what types of photos will you be
required to shoot? Many of the techniques covered earlier under Army tactical
ground photography are similar to those of ADP after suitable modification.
b. Obliques.
(1) Oblique aerial photographs are made with the axis of the camera and
lens deflected from the perpendicular. They fall into one of two categories:
(a) High obliques, which include the horizon line in the picture area
(fig 2-3).
(b) Low obliques, which do not include the horizon line but do take in a
large area of terrain (fig 2-4).
(2) All obliques
have the advantage of showing
the terrain features
from
a
more
natural
viewpoint,
that
is
as
the
scene
might
appear
