Physics of digital photography

Description

This book provides an overview of the detailed physics involved in the imaging chain for an audience of scientists and engineers. With the increasing use of digital photography in a research environment, modern scientists and engineers need to better understand the science behind digital photography to fully exploit this invaluable research tool.
