b. Differences in color are readily observable from the air.
Color
differences may result from the dying or wilting of either the foliage used
for camouflage or the trees, shrubs, etc., from which the foliage was taken.
Poor use of camouflage nets versus the surrounding terrain is a dead give
away.
3. Texture refers to the ability of an object to reflect, absorb and
diffuse light. It may be defined as the relative smoothness or roughness of
a surface. A rough surface, such as a field of grass, reflects little light
and casts many shadows on itself (Figure 1-21).
Consequently it appears
very dark to the eye or on a photograph.
A smooth surface, such as an
airstrip or the roof of a building, reflects more light on an aerial image.
Thus an airstrip, even though it might be camouflaged the same color as the
surrounding terrain, would show up as a tighter tone on an image.
The
absence of texture results in shine.
4. Shine is the most revealing breach of camouflage discipline. This alone
can attract attention to a location under observation. Shine is generally
associated with the reflection of sunlight from windshields, windows, mess
kits, and other such texture-less surfaces.
Even the lenses of field
glasses, when used in direct sunlight, can reflect a bright shine similar to
that of a mirror (Figure 1-22).
