It goes back to the camera obscura, a box with a small hole on one side. On the opposite side the light projects an image (upside down!) of the world outside. The hole is opened only for a short time, and the image of that moment is fixed by a film with a layer chemically sensitive to light. What was a hole is replaced by glass lenses. They allow to change the angle of the entering light, from very wide to extreme telephoto. The diameter of the "hole" can be varied in a lens. The focus can be chosen (or is chosen automatically by the camera), but cheap cameras still have a fixfocus as the camera obscura did. In the modern digital cameras the light falls not on film, but on electronic parts sensitive to light, and they give the information they receive to the memory card.
