Most of the camera works exactly the same as any other... there's a lens that focuses and a shutter that is normally closed, blocking light from passing through the camera, but opens when you want to take a picture. In a film camera, the light that gets through the shutter while it is open hits film, which is chemically sensitive to light. Digital cameras use a charged-couple device instead. This is a photosensitive (sensitive to light) computer chip, which converts the light energy into information that can be read by a computer.
how is a digital camera work ?
