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.
The eye is a slightly asymmetrical globe, about an inch in diameter. Just behind the iris and pupil lies the lens, which helps to focus light on the back of the eye. Most of the eye is filled with a clear gel called the vitreous. Light projects through the pupil and the lens to the back of the eye. The inside lining of the eye is covered by special light-sensing cells that are collectively called the retina. The retina converts light into electrical impulses. Behind the eye, the optic nerve carries these impulses to the brain. The macula is a small extra-sensitive area within the retina that gives central vision. It is located in the center of the retina and contains the fovea, a small depression or pit at the center of the macula that gives the clearest vision. Eye color is created by the amount and type of pigment in the iris.
