The Physics and Art of Photography, Volume 3

Detectors and the meaning of digital
John Beaver


This is the third volume in a three-part series that uses art photography as a point of departure for learning about physics, while also using physics to ask fundamental questions about the nature of photography as an art. This volume focuses on the physics and chemistry of photographic light-sensitive materials, as well as the human retina. It also considers the rudimentary nature of digital photography and its relationship to the analog photography that preceded it.

About Editors

John Beaver is a professor of physics and astronomy at the Fox Valley Campus of the University of Wisconsin Oshkosh, where he teaches physics, astronomy, photography and interdisciplinary courses. He earned his BS in physics and astronomy in 1985 from Youngstown State University, and his PhD in astronomy in 1992 from The Ohio State University. His published work in astronomy focuses on the topics of spectrophotometry of comets and gaseous nebulae, and multicolor photometry of star clusters.
