• Letsworks 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
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.
