Pinhole Cameras: For Science, Art, and Fun!
Button, Clare
Tech Directions, v67 n5 p21-24 Dec 2007
A pinhole camera is a camera without a lens. A tiny hole replaces the lens, and light is allowed to come in for short amount of time by means of a hand-operated shutter. The pinhole allows only a very narrow beam of light to enter, which reduces confusion due to scattered light on the film. This results in an image that is focused, reversed, and upside down. Because there is no lens, the depth of field that remains in focus is virtually infinite. That is, every image in the photo will have the same amount of focus. Having students make their own pinhole camera, take photographs, and develop their own picture gives them an excellent--and engaging--educational experience. This article describes a pinhole camera activity for students that will help them to better understand the function of a lens in the eye and other optical devices, as well as the properties and nature of light.
