A camera works similarly to the human eye. Light enters through the lens and is focused onto the light-sensitive film or sensor inside the camera. The film or sensor records the image when the shutter is pressed, similar to how light is focused onto the retina in the eye and the image is sent to the brain. Key components of both the eye and camera include the pupil/aperture to control light intake, a lens to focus the image, and a light-sensitive surface at the back to capture the image.

Work?!

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.
