Answer 2

Sibnce you r looking only for a short answer...Heres a concise form of what i know...

A pinhole camera is a camera without a conventional glass lens. An extremely small hole in a very thin material can focus light by confining all rays from a scene through a single point. In order to produce a reasonably clear image, the aperture has to be a small pinhole on the order of 0.5 mm (0.02 inches) or less. The shutter of a pinhole camera usually consists of a hand operated flap of some light-proof material to cover and uncover the pinhole. Pinhole cameras require much longer exposure times than conventional cameras because of the small aperture; typical exposure times can range from 5 seconds to hours or days.

The image may be projected on a translucent screen for real-time viewing (popular for viewing solar eclipses; see also camera obscura), or can expose film or a charge coupled device (CCD). Pinhole cameras with CCDs are sometimes used for surveillance work because of their small size.

In the arts, digital cameras encourage artistic experimentation due to the elimination of film and processing costs; as a result, some photographers have tried making their own pinhole lenses for digital camera bodies, usually using a body cap with an extremely tiny hole in the center. The results show significant optical aberrations, but can nonetheless be artistically pleasing. In addition, extensive post processing in image enhancement software such as photoshop can minimize much of the distortion, thus resulting in a surprisingly good image. However, in terms of quality and convenience, a pinhole lens is no match for a conventional optical lens.

Answer 3

I made my own pinhole camera with a quaker oatmeal box. It works really well, and it only takes like a day for the paint to dry so you can start using it the day after you make it.

heres the link with the directions. You'll need film paper and chemicals as well. I bought my film paper (some call it photographic paper) at a Ritz cameras at the mall, 5x7 works. I got 100 sheets for $20. The chemicals can be found on bhphotovideo.com. I got a safelight, trays, chemicals, and containers for around $50. Hope this helps!

Answer 4

Pinhole camera was one of the earliest versions of a camera,
long before cameras were manufactured. You can actually make a pinhole camera out of something like a quaker oatmeal container. Here is a website with images, and a complete explanation of how it works and how to make one:

Answer 5

See the ooooooooo's in your questions Well the lens on these cameras are as small as your ........ instead.
Colour or black and White.
Can see in the Dark with less that the light coming inside from out. Through a hole in your blinds where the string goes through.
With this little amount of light coming into a room.
The pin hole can not only see through a hole that small in a wall, book, or pack of cigs.
But can record video with just the amount of light that comes through that hole in the blinds into a totally dark room.
