A pinhole camera is used for capturing the movement of the sun for a long period of time. This is also known as solargraphy.

In a normal camera, a convex lens is used to admit more light while simultaneously focusing all that light to a small area. This reduces the amount of exposure time required. The effect of the size of the pinhole opening on the image formed is illustrated below.

To understand how a pinhole camera works, imagine yourself inside a dark room which allows no light inside. Now imagine a small opening made on the wall that you are facing. If someone were to hold a torchlight from the outside, you could see that light seep into your room. If the person with the torch moved around the light source, you would see the light seeping in, vary in terms of direction and even intensity.

You can make a simple pinhole camera with simple materials probably available at your own home. The stepwise procedure on how to make a pinhole camera has been described below.

Ibn al-Haytham invented the pinhole camera. He was an Arab scholar who studied the pinhole camera for the first time and used the camera to demonstrate how light can be used for the projection of an image onto a flat surface.

The pinhole camera is one of the earliest predecessors of modern-day cameras. Let’s explore the world of pinhole cameras.

Now instead of a room, imagine a small box with has been light proofed except for a small pin-sized opening on the box. Instead of you inside, there is a film which captures light rays. Instead of you looking at the image of light rays hitting the opposite side of the wall, the film inside the box records the image. The exposure to the light has to occur for a prolonged period because the pinhole opening limits the amount of light entering.

The pinhole camera is the simplest kind of camera. It does not have a lens. It just makes use of a tiny opening (a pinhole-sized opening) to focus all light rays within the smallest possible area to obtain an image, as clearly as possible. The simple image formed using a pinhole camera is always inverted.
