The potential audience for this book is very limited, for two reasons. Firstly, and obviously, it is for researchers in photography, who want to improve the performance of film. For example, by reducing the granularity or the surface tension. The book is not for the amateur photographer who maintains her own darkroom. Rather, it is for those developing new types of film.
The second reason for the book's limited appeal is the rise of digital cameras. The global customer base for film is shrinking continually. Granted, at some point, it will stabilise. All this means that few companies, even on the scale of Kodak, can afford to maintain an extensive research effort in film.
There is actually a third reason, which may be discerned from the book. The understanding of the physical and chemical processes in film is very mature. Film is a known technology which has probably been pushed to its performance limit. Future gains are likely to be very incremental. Whereas digital cameras (and this is a phrase which will soon be elided to just 'cameras') still have much room for improvements in their baseline semiconductor technology.
