th Although photography has its beginning in the 17 century, it was only
in the 1920's that photography emerged as a science. And as with other
s- ences, mathematics began to play an increasing role in the
development of photography. The mathematical models and problems
encountered in p- tography span a very broad spectrum, from the
molecular level such as the interaction between photons and silver
halide grains in image formation, to chemical processing in ?lm
development and issues in manufacturing and quality control. In this
book we present mathematical models that arise in today's p- tographic
science. The book contains seventeen chapters, each dealing with
oneareaofphotographicscience.Eachchapter, exceptthetwointroductory
chapters, begins with general background information at a level
understa- able by graduate and undergraduate students. It then proceeds
to develop a mathematical model, using mathematical tools such as
Ordinary Di?erential Equations, Partial Di?erential Equations, and
Stochastic Processes. Next, some mathematical results are mentioned,
often providing a partial solution to problemsraisedby the
model.Finally, mostchaptersinclude problems.By the nature of the
subject, there is quite a bit ofdisparity in the mathematical level of
the various chapters.
