In the photograph,
perspective, the partial
covering of objects in the
background by objects in the
foreground, shadow, and,
possibly, our familiarity with
the usual sizes of cacti and
other objects in the scene seem
the obvious cues that yield the
impression of depth. In
everyday life, binocular vision
ΓÇöΓÇôvision with two eyes rather
than oneΓÇöΓÇôis often said to be
the basis of our perception of
the world as three-
dimensional. How can we tell
whether or not these factors
are crucial and what others
may also yield information
about distance? After all, the
fact that binocular vision, for
example, is not necessary for
depth perception can be seen
simply by closing one eye and
looking at surrounding objects.
Similarly, familiar size cannot
be crucial, because our
perception of distance is often
veridical even when the objects
viewed are unfamiliar.
