A digital camera is an electronic device that records images digitally. To use a digital camera, you turn it on, set it to auto mode, focus on your subject, and press the shutter button to take a picture. You can view pictures on the camera's LCD screen. To transfer pictures to a computer, you install the camera's software, connect the camera to the computer with a USB cable, and use the software to import photos. Online photo sharing websites allow you to create an account to publish and share pictures with others.
