3. Shadow. The pictorial effect and analysis of a vertical photo are greatly influenced
by shadows.
a. The shape of an object is often more discernible from the shadow it casts than
from its vertical (top) view (Figure 1-3). By studying the vertical image of an object
together with its shadow, you can learn to associate the vertical appearance of that object
with its angular side view as represented by the shadow. This enables you to form a
mental image of the object as it would appear from the ground. An excellent example is a
bridge, the shadow of which frequently reveals the construction of a bridge's supporting
structure. Also, shadows allow the identification of electronic installations by revealing
their characteristic antenna construction.
