Other effects have a similar
explanation. Consider, for
example, the case of objects
depicted as jutting out toward
the observer, for example, a
snapshot of someone reaching
straight out to wave at the
photographer. Viewed from the
side, the arm still seems to
reach out toward us. If we
viewed a real arm outstretched
in this way from the side, it
would project quite differently:
as we moved to the side of the
real person, the projection of
the arm would become
increasingly horizontal. But
when we view the picture from
the side, the orientation of the
arm in the picture remains
more or less unchanged, and we
continue to see the arm
pointing toward us.
