[Annabelle] **//__ Digital cameras __//**

A digital camera is a camera that takes videos or photographs (or both) digitally by recording images via an electronic image sensor. Many digital cameras can record moving videos as well as record sound. Digital cameras can do things film cameras cannot: displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, recording video with sound, and deleting images to free storage space. Digital cameras use a lens to see things; sometimes they use a flash of light to strengthen the edges of the image in the dark. []
