The Pinhole Camera The simplest camera uses a tiny hole as a lens. Light falling on such a "pinhole" emerges on the other side and creates an image on a screen some distance from the hole. For a sharp image, the hole needs to be very small. This means that only a small amount of light will be let through, so the image that's formed will be dim. We considered using a pinhole for the "lens" on the castaway camera, but decided that there wouldn't be enough light.
