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.
Is the image on the screen of a pinhole camera back to front?
Yes, the image on the screen of a pinhole camera is upside down because of the way light passes through the small aperture and projects onto the film or sensor inside the camera. It is a characteristic of pinhole cameras due to the nature of how light travels through a small hole.
Why is the image formed by a pinhole inverted?
The pinhole camera works based on the principles of light traveling in straight lines. As light passes through the small opening, it creates an inverted image because the upper part of the object is directed downward and vice versa. This inversion occurs due to the way light rays converge and intersect at the pinhole.
Why would a photographer use a pinhole camera?
probably to take a picture of something very bright, like the sun. In reality, the pinhole camera is not the ideal instrument for taking photographs of the sun. It is used instead to create certain specific effects in the photograph. Light passing through the pinhole is not brought to a sharp focus on the image plane in the same way a lens would, so the sharpness of the image is limited, and dependent on the size of the pinhole, the distance of the pinhole from the film plane, and the amount of diffraction from the edges of the pinhole. Even with optimum sharpness, the image will be very soft, with fairly fuzzy outlines. In the hands of a skilled photographer, the effect can be very pleasing.
Who invented the first photography?
The first known photograph was taken in 1825 by "Niecphore Niepce." however the camera obscura and pinhole cameras were developed before that, they just had no way of recording the image that was produced.

How is the image formed on the film of a camera?
In a camera, the light from the subject is refracted by the camera lens, and focused on the film or digital receptor inside the camera. The lens is taking the "large image" and shrinking it to a smaller size, and this small image becomes the digital image (or the negative image on film).How a Camera WorksA camera is any sort of light tight chamber (the word camera means "chamber" in Latin) with a pinhole or convex lens in one side. The lens is what "forms" the image on the opposite side of the camera. Your eyes are cameras! They are light-tight chambers with convex lenses which form continuous images on the retinas (light sensitive surfaces) at the backs of your eyeballs. Because of the way light passes through a pinhole or lens, the image is projected to the back of any camera upside down. This is just as true in your eye as it is in your camera! But, you protest, I don't see upside down! No, you don't, because your brain "flips" the image right side up as it comes from your optic nerve. Your digital camera does the same thing electronically before it delivers the image to your viewscreen.Sight, and your camera, works because objects reflect light. Even black objects reflect some light. Lighter colors reflect more. The pinhole or lens in any camera is gathering light as it comes reflected from a scene. The light reflected from the scene is scattering in all directions, but as light from what you see reaches the pinhole or convex lens in your camera or eye, you can try imagining that the light rays from the scene must bendand squash down (we say converge) in order to pass through the pinhole or lens. Inside, the light rays must cross, which is why the image projected to the back is upside down. If the lens is the correct distance (focused) from the back of the camera, the lens will form a sharp image on the side opposite the lens, which can be your retina, film in a film camera, or the sensor in a digital camera.There's lots more to know.

It has a fun, easy project for any age for making a pinhole camera that you can look inside and actually see the upside down image projected onto a translucent screen made of waxed paper.
How does a Pinhole camera work?
A pinhole camera is the most simple form of Photography and requires practically no knowledge of photography to build a pinhole camera and capture an image using it. The basic principle behind a pinhole camera is the light enters through the pinhole at the front of the container (eg. a shoebox) travels through the light proof box and hits the photographic paper at the back of the box. The paper reacts to the light and where the light falls it is exposed (dark) and where there is no light the paper remains light. As you will be able to see after the image has been developed; the image produced will be a negative of the actual image. The image will also be upside-down due to the way in which the light enters the box. Then all that remains is to develop the photographic paper as you would normally. You will not see anything until you start to develop the paper. The paper will still appear white. Remember: - Light only travels in straight lines, - The box will need to be light proof apart from the pinhole at the front, - The pinhole cannot be too small, it can quite easily be too large, - Only place the paper in the box and remove it from the box in a darkroom. - Anything can be turned into a pinhole camera! Even rooms... Suggestions: - An old shoebox works well, as does a film canister. - Use black and white paper, it is easier to develop and far simpler to start with. Maybe experiment with colour afterwards. - You will need to use trial and error to find the correct exposure time. eg, if the image appears too dark decrease the exposure time, if it appears too light increase the exposure time. Have fun, pinhole camera's are great to make and a good introduction into photography. Alex Apps **************** - the aperture should be about 1/100th of the distance to the image plane visit http://en.wikipedia.org/wiki/Pinhole_camera for a fascinating story about the world's largest pinhole camera Micron
