Digital photography uses a digital camera. Sometimes it is called "digital imaging". Like other cameras a digital camera has a lens, aperture, and shutter. The picture the lens makes is recorded by a light-sensitive electronic sensor. A digital camera does not use photographic film to record a picture. Digital photographs are stored in storage devices such as SD cards. They can later be transferred to a computer. Paper prints can also be made from digital pictures. Digital cameras are also not expensive to use, as there is no film to buy.
