5 Examples of Pin Hole Camera Pictures







What is a pinhole camera?

A pinhole camera is a simple camera without a lens and with a single small aperture — effectively a light-proof box with a small hole in one side.

How does a pinhole camera work?

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.
Smaller holes will result in sharper images, and larger holes will create more diffuse images. 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.
