The Eye as a Camera
A camera and an eye function
in a similar manner, but the
analogy has its limits.
As schoolchildren, most of us
learned a simple and appealing
explanation of why things
appear to us the way they do,
based on the analogy of the eye
as a camera. According to this
"theory," the eye takes
"pictures" of the scenes before
it. Light reflected from objects
in the scene is focused by the
lens inside the eye onto the
retina, the "film" at the back of
the eye, to form images. These
images are then transmitted to
the brain, generating mental
representations of the scenes--
our perceptions.
