This Book is a Camera

Authored by artist and designer Kelli Anderson, IThis Book is a Camera/I is a pop-up book that turns into a fully functional pinhole camera. It serves as a fun and educational way to learn about the basic principles of light while also making your own photographs. 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. Easily turn a bathroom or closet in your home into a darkroom and process photos using household supplies (baking soda, instant coffee and water). Your photos will cast your modern life in the warm analog glow of 1840s technology. The book includes: a piece of paper folded into a working 4x5" camera, a lightproof bag, five sheets of photo-paper "film," development instructions (for household ingredients or photo chemicals), a companion lightmeter app for iPhone and Android (but any light meter will do if set to ISO 10 and f/228), and a satisfying demonstration of the connection between design science/structure function. Originally published by MoMA in 2015, this innovative bestselling activity book returns to print.brBKelli Anderson/B is a graphic designer, paper engineer, educator and author who uses design magic to connect people with the hidden talents of everyday things.
