#85 Camera Obscura

First, punch a hole in your roof. Then arrange a mirror and lens to project light through the hole onto a horizontal screen. That’s a camera obscura.

In Cadiz, we visited one (that's me on the left, Mary on the right). Cadiz is surrounded by ocean on 3 sides, so watching the ships come in has been a local tradition for centuries. With the camera obscura, you can watch the ships come in all day and never get rained on or sunburned. It’s the low-tech version of a video camera and monitor…no electricity-no problem. Now I want one. Do you know anyone who has the home version of camera obscura?

Yours in low-tech gadgetry,
