(c) With the oblique photo, either high or low, you are looking at
the side view or under any overhead obstructions.
Obliques are ideal in

This view also gives the aircraft
vulnerability to AAA fire.
The problem with obliques is that it is
difficult to see enemy positions on the reverse slope or behind heavy stands
of trees (Figure 1-6).
