What is the difference between the pinhole camer and the human eye?
The pinhole camera has no lens. The human eye has a variable-focus lens.
Pinhole camera and human eye similarities?
I think a pinhole camera is similar to the human eye because like the pinhole camera when it sees something it reflects the image but it is an inverted image. With the human eye the brain corrects it and turns it the right way up. The pinhole cameras image is not corrected because it does not have a lens.
How is the human eye different to a pinhole camera?
Absolutelly No idea Guys
How does the human eye relate to physics?
The human eye works in a similar way to a pinhole camera with three refinements: a) an adjustable pinhole size controlled by the iris; b) a fixed converging lens across the pinhole called the cornea; c) an adjustable converging lens to focus at different distances, controlled by the brain.
Why is vision sharpest when the pupils of the eye are very small?
It's like looking through a pinhole.
Explain in your own words how this simulates how the lens in the eye works?
A pinhole camera simulates how the lens in the eye works because it reflects an image onto an interior surface, such as the retina of the eye.
Why is the image formed by a pinhole inverted?
An inverted image is formed in a pinhole camera because the light rays coming from the top and the bottom of the object intersect at the pinhole.
What has the author Eric Renner written?
Eric Renner has written: 'Pinhole Photography' 'Bibliography of pinhole optics in science and art from the 5th century B.C. to 1850 A.D' -- subject(s): Bibliography, Geometrical optics, Photography, Pinhole, Pinhole Photography
Can pinhole cameras use a con flex lens?
No, because pinhole cameras don't have any lens.
Why pinhole camera has infinite depth of field?
A major advantage of a pinhole over a simple (or not so simple) lens is "infinite depth of field." To see this for yourself poke a pinhole into a thin sheet of opaque material and hold the pinhole close to your eye (if you wear glasses, take them off). Hold one of your fingers a few inches in front of the pinhole and notice that your finger is about the same clarity as everything else beyond. That's infinite depth of field. A more or less scientific explanation for depth of field is that an optical image is made of of very tiny "circles of confusion." When the circles of confusion are small enough, they are called "points" and the optical image is considered to be in focus. Therefore, points of focus. A pinhole camera has infinite depth of field because the pinhole creates circles of confusion the same size as the pinhole all over the inside of the camera, and the little circles of confusion are small enough to be regarded as points of focus. These have a high enough resolution to be acceptable as a coherent image. Photographers can use a small aperture to increase the depth of field, but except for rather uncommon lenses, the depth of field is not very extensive compared to a pinhole image.Source: The Beginner's Guide to Pinhole Photography By Jim Shull
What is the meaning of the word 'pinhole'?
A pinhole usually describes a very small hole having a diameter equal to that of a sewing pin. A Pinhole camera is a simple model without a lens and with a small aperture.
What is a stenope?
Sténopé is French for pinhole.
