There's a reason why people say this book reads like a textbook: it _is_ a textbook. As stated in the blurb on the back cover, it a college-level introduction to photographic theory. The theory in question is not that of optics or photochemical reactions or analog-to-digital conversions. Rather, it is the Theory with a capital T of academic postmodernism - "pomo" - the same Theory that presents itself in Film Theory and Literary Theory and the all-encompassing Cultural Theory.
You may have encountered postmodernism in school or in your personal reading. If you did, you will have some idea of what you will find in this book. If not, don't worry about it. The New York Times photography critic Andy Grundberg declared the death of postmodernism in 1990, film theoreticians David Bordwell and Noel Carroll followed suit in their book Post-Theory in 1996, and A-list literary critic Fredric Jameson drove the final nail into the coffin in a New York Times article in 2003. Postmodernism, as the dominant academic fashion, is a thing of the past. It was on its last legs when this book was originally written and it is now definitely over. As such it's not something that you should feel you need to invest in, just make enough sense of to follow what the book is saying.
Though only one name, Liz Wells, appears on the cover, the book is actually the work of six authors, each of whom, including Wells, contributed a chapter or two. All the authors appear to be English and all are (or were at the time of writing) affiliated with British regional universities. The book was originally published in 1996. The third edition, reviewed here, was published in 2003.
The book contains seven chapters, an overview chapter and six chapters on individual topics. The chapters present surveys of articles and books (especially British ones) written on the topics, with lots of quotes from academics and relatively few from practicing photographers. There are bibliographical and other notes in the wide margins of the main text but, rather surprisingly for an introductory textbook, no annotated bibliography or "Further Reading" sections either at the ends of the individual chapters or at the end of the book. Several chapters include one or more case studies, which amount to extended sidebars purporting to demonstrate the application of the theory under discussion to specific photographs or photographic genres.
Based on a single quick read I would say that the quality of the chapters is uneven, ranging from pretty good through OK down to questionable. One or two of the case studies were interesting but most seemed to contribute little if anything to the book. Here, for what they are worth, are my impressions of the chapters (my headings; actual titles can be seen in the Amazon "Look inside this book" pages):
Ch. 1 Overview by Derrick Price and Liz Wells - unstructured, rambling, surprisingly poor; I would recommend skipping over it on the first read and going directly to the topical chapters. However the case study on Dorothea Lange's iconic Migrant Mother is the best in the book and should be looked at even if the rest of the chapter is skipped.
Ch. 2 Photojournalism by Derrick Price - one of the best in the book, very clear, well connected to the history of (British) photography, interesting.
Ch. 3 Personal photography by Patricia Holland - pretty good, genuinely thought-provoking at times, for example in its discussion of the tension between the idealized representation of domestic life in family albums and the often less than ideal realities hiding behind (and occasionally peaking through) the pictures.
Ch. 4 Photography of the human body by Michelle Henning - attempts to present a feminist perspective but tends to get stuck in the rhetoric and not reveal much about the actual work being talked about.
Ch. 5 Advertising (esp. fashion) photography by Anandi Ramamurthy - not as compelling as it could be but makes some interesting points, for example relating to stock photos and image banks and the commercial need for photographs created without, or later detached from, any specific context or meaning. The case study on the controversial Benetton ad campaigns of the late 80's is worth reading.
Ch. 6 Photography as art by Liz Wells - pretty good but focuses on historical debates and doesn't consider the forces that have caused recent changes in art photography (new objectivity/deadpan, influence of cinema, aftermath photography, etc.). The case studies on Surrealism and Landscape photography (one of the author's specialties) could have been among the most interesting but are actually very lackluster.
Ch. 7 Photography in the digital age by Martin Lister - the oddest chapter but in some ways the most satisfying. It's the one chapter that was significantly changed for the third edition. The author seems to have left the earlier version more or less as it was but added what amounts to an extended postscript that says that what comes before it is wrong. The change of heart centers around the question of the impact of the advent of digital imaging on the connection between the photograph and reality. In the original version of the chapter he says that digital imaging invalidates the connection and ends photography as we know/knew it. In the postscript he says that things actually didn't change that much, that most digital images retain their connection to reality and that, even if some clearly don't, there have always, since the earliest days, been photographs that present something more or less different from literal reality - a theme that actually runs through the whole book and may be considered its central point.
My main feeling about this book is that I wish it were better. I wish were clearer and better structured, I wish it were more up-to-date and less encumbered by the intellectual cruft of academic postmodernism, and, finally, I wish it were less Anglocentric and paid more attention to photography of North America, Europe, and the rest of the world. Still for all that it is not a bad book, and I give it three stars.
