Each single ray of light that reflects from a single point on an object does so in an infinite number of directions. The job of a lens is to gather and focus as many of these rays, which have slightly different angles of incidence, as possible. Since there is no lens in a pinhole camera, the method of control is to allow only a few of the rays from a single point that are close in angles of incidence to pass and land close together on the image plane. This can only be done by using a small opening.
it is used to prove the fact that light is rectilinear in motion
A pinhole camera image will be dim with a small hole because not much light rays are able to get through the hole.

Who told you it was sharp? It is anything but.
because you can take it any where and it takes loads of infomaition

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.
a pinhole camera has a very small aperture for the light to pass through. Thus the sharp focus distance is very great too. You will get a bigger image if you move your paper or whatever the image lands on, further away from the pinhole.it may not be as bright, though
Yeah, easiest is to build a pinhole camera. http://www.pinhole.com/ Or read: "Pinhole Photography" by Eric Renner
You can figure out why an image in a pinhole camera is upside down if you think about how the light travels to get to the image. Light from an object higher (or the top of the object) than the camera travels in a straight line down to the camera. It goes through the pinhole and continues heading down until it hits the back of the camera. This means that the image of something higher than the camera is now low in the image. The opposite is true for light from an object lower than the camera (or the bottom of the object): it travels to a point higher in the image. Still does answer my question, how did the image get upside down? answer was no concusive.
it is a camera which is very useful to us more than simple camera.

A pinhole camera has special paper put inside of it, absorbing the light making lots of shadows ect.
