Preface

Shine diffuse light on a developing photograph, and continued development yields an amazing result: part of the image is positive, and part of the image is negative! The process (usually called solarization, but sometimes called the Sabatier effect) is looked upon by most photographers as completely mysterious. In this book I try to remove the mystery from solarization by describing its history, by showing how it can be used in both art and science, and by explaining how it works from a scientific point of view.

Publication of this book on the website of the College of Chemistry of the University of California at Berkeley would not have been possible without help from my wife, Jane Vavra Jolly, and the staff of the College Computing Services and Network Services, to whom I am very grateful.
