This is a working camera that lives in a pop-up book. The book concisely explains—while actively demonstrating—how a structure as humble as a folded piece of paper can tap into the intrinsic properties of light to produce a photograph.

The book includes:

-A piece of paper folded into a working 4x5" camera

-A lightproof bag

-5 sheets of photo-paper "film"

-Development instructions (use household ingredients or photo chemicals)

-A satisfying demonstration of the connection between design & science/structure & function

-A companion lightmeter app for iPhone
