In 1973, Steven Sasson, a young engineer, went to work for Eastman Kodak. Two years later, he invented digital photography, and made the first digital camera.
Digital cameras capture and record images using digital technology. Digital cameras look very much like ordinary cameras that use films, but they work in a completely different way.
When you press the button to take a photograph with a digital camera, an aperture opens at the front of the camera, and light streams in through the lens. But there is no film in a digital camera.
Instead, there is a piece of electronic equipment that captures the incoming light rays, and turns them into electrical signals. All digital cameras have a built-in computer, and all of them record images electronically.
A digital camera has many advantages. It gives us instant photographs, allows us to edit our pictures, and makes it easier for us to share photographs.
