On the cliffs above San Francisco's Ocean Beach perches a landmark observatory—a giant camera obscura that uses natural light and a pinhole to capture a continuous real-time image of the ocean and rocks below. Step inside the camera obscura with operator Robert Tacchetto and see how this centuries-old technology creates enchanting images of the outside world.
