Other factors can also weaken
or destroy the illusory effect. If
the texture of the photographic
image or the surface of the
painting is visible, it will lead
to the perception of an ordinary
picture on a surface. If the
picture is nearby, oculomotor
or retinal disparity cues may
inform observers of the
presence of a flat picture
surface, or the frame of the
picture may provide this
information. Pozzo was able to
circumvent all these problems
because the ceiling was roughly
100 feet above the floor.
Spectators do not perceive the
surface of the ceiling as such,
even viewing it binocularly.
Pictures of this kind,
pictures that are not perceived
as pictures, are remarkable
achievements, tributes to the
great skill and knowledge of
their originators. They are also
acid proof of the efficacy of
pictorial cues. In such
pictures, nonpictorial depth
cues either are absent or
contradict the pictorial cues;
yet the scenes depicted appear
vividly three-dimensional.
Among works of art, however,
trompe lΓÇÖoeil productions are
exceptional, and perception of
them differs from the
perception of other pictures.
Even within the domain of
aesthetics it can be argued that
trompe lΓÇÖoeil productions are
not really examples of
paintings qua art. For a
painting is meant to be seen as
a painting, as representing
something else but at the same
time as an object unto itself.
