Air-to-air photography, as the name suggests, is
photography taken from the air of a subject in the air,
usually another aircraft. Air-to-air photography
techniques are discussed later in this chapter.
TYPES OF AERIAL PHOTOGRAPHY
The vertical and oblique categories of aerial
photography are divided into several types of aerial
photography. Types of aerial photography are
designated by their composition. A PINPOINT aerial
photograph contains a target small enough to be
included in one exposure. Long, narrow targets are
photographed by making a series of overlapping
exposures, called a STRIP When several strips are
pieced together to form one composite picture of a large
area, it is called a MOSAIC. Two pictures
photographed to provide a three-dimensional effect are
called STEREO aerial photographs. However, there are
some characteristics that all types of aerial photography
must have. All aerial photography must be sharp, show
great detail, and be composed properly, so it satisfies
the need for which it was made.
Pinpoint aerial photographs are usually made when
the target, such as a building, a weapon, or a small
encampment, is small enough to be included in one
exposure (fig. 4-6). In the case of oblique photographs,
you can make more than one shot of a pinpoint target to
show the target from different angles. For instance, you
