Camera obscura means “dark chamber.” Light entering a darkened room or box through a small opening projects an inverted image of the world outside. That optical arrangement helped give rise to the photographic camera.

### The room inside camera

Imagine stepping inside a camera. There's room to stand. On the wall, the world outside hangs upside down. A camera obscura can be an entire room, and its image moves as the world moves. Keeping that image after the light disappears requires another invention: a way to record it.

- Six letters, with A appearing twice.
- Standard English Scrabble tile values total 10 points: C(3) + A(1) + M(3) + E(1) + R(1) + A(1), before bonuses.
- A camera obscura can project a moving scene without electricity.
- Projection and recording are separate operations: a camera obscura can show an image without preserving it.
