Physics of digital photography /

Mostrar otras versiones (1)

Physics is fundamental to all aspects of digital photography. This book works through the physics underlying the photographic imaging chain, from image capture through to the production of a viewable output digital image. It provides an invaluable insight into the connections between imaging science...
