Welcome to Camera Obscuras.com

I’m George T. Keene, an engineer who designs, builds and installs custom camera obscuras around the world. My work began in 1997 when I made my first CO in California. I built this site to share information and features about my projects.

The Camera Obscura

Invented centuries ago as an aid for artists, the camera obscura brings the outside inside. From its humble beginnings as a pinhole camera, the modern device can be a fully adjustable instrument that reveals insects around a nearby streetlight, traffic on distant freeways or smoke from the wheels of landing aircraft. The image is projected as a moving, full-color display viewed by a group of people in a darkened room.

The camera obscura appeals to observers of all ages and interest – landscape views, clouds, sunsets, moon, sun and planets – all are revealed while you remain comfortably seated inside your own motorized telescope
