How Does a Pinhole Camera Work?
- Pinhole cameras are the one of the simplest and oldest types of cameras. In a pinhole camera, light passes through a light-proof container through a tiny hole. The light streams through the box and projects an image on the back of the box's interior, to which a piece of film has been affixed. An image then develops on the face of the film much in the same way that it does in a typical 35mm film camera. It is possible to purchase pinhole cameras, but most users choose to make their own. Pinhole cameras can easily be made from common household objects
- Because pinhole cameras have no focusing apparatus, the size, shape and distance of the hole from the film are important. Smaller holes will result in sharper images, and larger holes will create more diffuse images. However, the size of the hole also determines the amount of light exposure necessary to develop the image: smaller holes will require longer exposures, and larger ones will require shorter exposures
- In order to determine the proper diameter of the hole, the distance from the hole to the film at the back of the camera must first be measured. This distance is called the focal length. A mathematical formula can then be used to determine the size of the hole. One common formula used states that the diameter of the hole (d) = 0.0073 multiplied by the square root of the focal length (f)
- Whereas most modern film cameras have an exposure time of a fraction of a second, the exposure time for pinhole cameras is much longer by comparison and can range from a few seconds to a few hours depending on the desired effect. Exposing the hole for a few seconds will produce a still image if the scene was posed and none of the objects in the field moved
