Artist and designer Kelli Anderson just released her latest book This Book is a Camera, a pop-up book that turns into a fully functional pinhole camera. The book acts as a simple educational tool to help explain how photography worked before we all had camera phones in our pockets. Anderson points out that making a simple camera obscura really isn’t too difficult and provides instructions on how you can make one yourself.

This Book is a Camera comes complete with a starter pack of B/W Ilford photo paper and instructions on how to use the camera to take photos. You’ll still need to pick up some developer fluid and have a dark room to develop photos in. Stay tuned for Anderson’s forthcoming This Book is a Planetarium from Chronicle Books.
