Camera and the eye... Ooooh. XD
Friday, August 3, 2007


Camera and the Eye

Similarities:
Aperture and Pupil
-opening for light to enter
Diaphragm control size of aperture and Iris muscles control size of pupil
-control the amount of light entering camera/eye
Glass biconvex lens and Cornea; lens, aqueous & vitreous humor
-refract light
Photosensitive chemicals on Film and Photoreceptors(rods & cones) in Retina
-object of light action to form image
Dark internal surface and Pigmented, dark choroid
-absorb excessive light to prevent multiple images formation

Difference:
Change distance between lens & film and Change focal length of lens using ciliary muscles
-focusing mechanism
