Camera

A camera is a device that captures images by recording light, either on film or, in modern digital cameras, on electronic sensors.

How it works

Light enters through a lens and is focused onto a light-sensitive surface. A shutter controls how long the light is let in, capturing a still photograph or moving video.

Uses

Cameras are used in photography, film, security, science and, increasingly, in smartphones carried by billions of people.
