Every modern camera is still a camera obscura. The principle of the "pinhole camera" has been known since the "ancient Greeks", for at least 2300 years. With the invention of ground glass lenses 400 years ago, the camera obscura became a practical tool for painters who wanted to draw the most accurate picture of nature possible. Ingenious scientists eventually turned it into "photographic cameras".
With this experiment kit you can build your own camera obscura, experiment with a glass lens, learn the old tricks of the inventors and how today's cameras work.
