Each image can be made up of more than a million pixels. The digital camera stores each image on a small disc drive. When you are done taking pictures or when the disc is full, you can hook a digital camera up to a computer and download the images. A motion picture camera and camcorder are similar types of cameras. They come in many sizes, from the small ones that almost fit completely into your dad's hand to the big ones Hollywood directors use.
Film goes through the camera but stops quickly to expose, or imprint images on, each frame.
Frames go through a camera very fast, at 18 or 24 frames a second. A little metal thing called a claw hooks into holes on the film's edges, pulls the film into place, retracts while the frame is exposed, and does the same thing all over again for the next frame. All this is powered by a tiny electric motor. Click above to see a drawing of a digital camera Click above to see a camera's parts Click above to see how light enters through the lens.
