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.

- the aperture should be about 1/100th of the distance to the image plane

How does a sensor chip work in a pinhole camera?
In a pinhole camera, a sensor chip captures the light that passes through a small aperture (the pinhole). When light rays enter the camera, they project an inverted image onto the sensor chip, which is sensitive to light. The sensor converts the incoming light into electrical signals, which are then processed to create a digital image. This process allows the camera to record the visual information captured through the pinhole.

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 can the image in a pinhole camera be made bigger?
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
Pinhole camera for sun?
A pinhole camera is a simple device that can be used to project an image of the sun without the need for lenses. It consists of a dark box or tube with a tiny hole (the pinhole) on one end and a surface (like photographic paper or a screen) on the opposite end to capture the image. When sunlight passes through the pinhole, it creates an inverted image of the sun on the surface inside the camera. This method is safe for observing the sun, as it prevents direct eye exposure to harmful rays.
How does a pinhole camera work to capture images?
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and project an inverted image onto a surface inside the camera. The image is then captured by the surface, such as film or a digital sensor, creating a photograph.
Why doesn't the Pinhole camera model always work in real life?
Pinhole cameras do work in real life. They just do not produce as good a quality of picture as most of our fancy high-tech cameras do. Partly, that is because you cannot regulate the light as well with a pinhole camera.
What camera came after the pinhole camera?

How does a pinhole camera work to capture images without the use of a lens?
A pinhole camera works by allowing light to pass through a small hole (the pinhole) and onto a light-sensitive surface inside the camera. The pinhole acts like a lens, focusing the light to create an image. The image is then captured on the surface, such as film or a digital sensor, without the need for a traditional lens.

What is the superiority of pinhole camera?
The pinhole camera is simple and requires no complex lens-based optical systems to work effectively as an image maker. In its simplest form it is no more than a light-tight box with a pinhole on one end and a place for a sheet of light sensitive material on the other.
When was the pinhole camera made?
