The word aperture refers to the diaphragm opening inside a photographic lens. it works in a similar way to the iris in the human eye. Just like the iris regulates the amount o â¦ f light that passes into the eye by closing and opening, the size of the diaphragm opening in a camera lens regulates the amount of light that passes through the lens onto the film inside the camera at the moment when the shutter curtain in camera opens during an exposure process.
EYE STRUCTURE AND FUNCTION Eye is like a camera. The external object is seen like the camera takes the picture of any object. Light enters the eye through a small hole called the pupil and is focused on the retina, which is like a camera film.Eye also has a focusing lens, which focuses images from different distances on the retina. The colored ring of the eye, the iris, controls the amount of light entering the eye.It closes when light is bright and opens when light is dim. A tough white sheet called sclera covers the outside of the eye.
