Perspective in the age of digital photography

ISBN 978 0 954 6562631

Published June 2012

When you take a photograph, you flatten the world. This remarkable process is called perspective. In a clear, non-technical way, this book provides an introduction to perspective through looking at photographs. It covers practical issues such as what happens when photographs are joined together, and why photographs still look realistic when viewed obliquely. This is a book for anyone interested in perception, photography or geometry.
