How is a camera like with an eye?

Question

How is a camera like an eye? Which parts of the camera

i) bend incoming light

ii) control the amount of light falling in the film

iii) act as the screen, like the retina of the eye

Answer 1

Go to http://www.popphoto.com and search for the article "The Photographer's Guide to the Eye". Its in the Aug. 2008 issue.

Answer 2

The lens always controls the light coming onward, and the shutter as well as shutter speed is what controls the amount of light or saturation which comes directly into the picture.

As such, lenses have a very important purpose with any camera. They function as the means to which proper resolution and picture quality are transferred. No Digital Camera is a truly good camera, without a tightly knit quality lens backing it up.

Biology teachers have been telling students "the eye is like a camera" ever since there were cameras. And while there are many similarities between the two, the camera, alas, is not like an eye. The human eye is a deceptively simple biological organ made of wet, squishy materials that efficiently and rapidly manipulate and process light waves under a diversity of conditions. A camera—even modern digital ones—not so much. They are hard, and flat and brittle.
