How an eye
Start With...
• Light enters the eye through the pupil, the
dark center of the colored iris
• Next, light passes through the lens which
expands or contracts to focus an image
• Then the light hits the back of the eye which
is lined with the retina
• The retina is lined with photoreceptors that
translate the light into electric impulses sent
along the optic nerve to the brain

5. How the Camera
• Works
Light enters the lens and passes through the
aperture (*pupil) .
• Then light is focused upon by adjusting the
camera lens (*lens).
• The light hits the film or camera sensor inside
of the camera (*retna) where it creates and
records an image.
• When a shutter button is pressed the shutter
closes, blocks light from the film/sensor so
that it can record the image.
