What is the difference between camera and pinhole camera?

Answer 1

I'm looking for the same answer,someone reply!.

cos' when i look on Google it suggests the similarities but not the differences-.-

c'mon people:L.

answ2. have a crack at Pinhole Camera in wikipedia.org, and similarly with eye.

Answer 2

Cameras take and make a moment last forever while your eyes can only savor a moment for a second
Camera can record and show everything later. They're actually fairly similar in overall principal. They both have a lens which focuses light on some type of light sensitive material. The camera focuses light on film or a electronic photosensitive plate. The eye focuses light on the retina which is made up of thousands of light sensitive cells called rods and cones. These are attached to nerves that carry the messages of light to the brain which interpreters what you are seeing.

Answer 3

The contemporary camera is an electromechanical device, and the eye is a biological mechanism. Both have a lens to respond to and focus electromagnetic energy (light), but the eye puts the light on the retina of the eye. This biological "film" immediately transmits information to the brain, and we are thus able to see. In the camera, the "film" is either a chemical emulsion on plastic or an electronic matrix that captures the light. In the former, the film undergoes chemical changes in response to the light. In the latter, electrical signals arise because of the affect of the light on the semiconductor matrix, and this information is stored electronically in some kind of storage media or device. Either subject can have a book written about it, and there are, in point of fact, books on the function of the eye and on vision, and also on electronic imaging. The camera has been advanced to be able to see outside the optical spectrum the eye is sensitive to, and we continue to push the envelope with advancing technology. We have high speed cameras, and the images from satellites show us things we could never resolve with our eyes. But the eye is a most amazing biological mechanism. And it is connected to the most amazing biological machine we know of -- the human brain.

Answer 4

A human eye does the same as a camera lens, but instead, it captures the information in the retina, and sends if through the optic nerve. A camera lens does the same, but, using the light, it sends it through the camera, bouncing off mirrors and arriving to your eye.

Answer 5

A pinhole camera you make yourself control the shutter speed (usually a piece of cardboard) manually by pulling it up and down. The image is then burned onto film. The difference is that most regular cameras have a sensor so that your pictures would be over or under exposed. Also with a pinhole camera the is a huge risk of ruining your film because some unwanted light snuck into the interior of the camera. The pictures will also be poorer quality than that of a regular camera. There are many more differences but that's the gist of it.

Answer 6

hi!

they both have lenses

they both display a picture upside down but the brain iterprets this as wrong so it flips it the right way round !

:D

Answer 7

A pinhole camera is similar to the human eye because light travels from a scene into the hole or eye and this produces the image.

Answer 8

They aren't. An eye has a lens and an adjustable iris, neither of which a pinhole camera has.
