The most primitive type of camera there is.

  1. Take a light-sealed box.
  2. Poke a hole in the center of one end, and cover it up.
  3. On the opposite face of the hole, lay some photographic paper flat the back.
  4. Point your box, hole-first, at something that doesn't move.
  5. Uncover the hole.
  6. Wait about a minute or so.
  7. Cover the hole.
  8. Go back to your darkroom and develop your film.

Assuming you got your exposure time right, you should have a picture of your object, with an extremely high depth-of-field.
The camera type that Ansel Adams used was basically a pinhole, except that his 'pinhole' was actually a very expensive single lens.
