The Keepers of Light: Book Review

This book takes its subtitle - "A History and Working Guide to Early Photographic Processes" - quite seriously. It is as much a history of early photography as it is a practical guide to early processes. So, while most handbooks for these processes have a bit of history included for 'background' as a matter of course, Crawford dedicates the major chunk of the book to a detailed, sustained and quite insightful history of early photography. The practical guide to these processes is quite competent but it is almost an afterthought after the exhilarating tour-de-force of the first section of the book on the development of photography from its earliest days to well into the age of the silver gelatin print in the first half of the twentieth century.

I have always found most histories of photography to be quite tedious. They usually read like a long list of dates and developments and brief backgrounds of the persons associated with them. This approach is akin to the older sort of history as a narrative of the rise and fall of kingdoms and rulers - a history based around personalities and a more or less linear notion of progress. But Crawford takes a leaf out of newer historians who write social history not as a linear narrative but as a 'genealogy' of inter-related strands perpetually interacting with each other - 'history from below.' Of course, he isn't writing with the grand developments within academic historiography in mind, but his approach makes this a very apt comparison.

The Keepers of Light lays out the evolution of what Crawford calls the 'syntax' of photography. The first chapter uses the examples of traditional printmaking and painting very effectively to lay out what exactly constitutes a 'syntax' for a visual medium. The parallels to modern theories of linguistics and semiotics are unavoidable and Crawford uses them very effectively to illustrate his point that every visual medium has a basic 'vocabulary' and 'ordering pattern' which combine to produce a coherent 'meaning' for the observer. This can be constituted of the most basic elements like the direction and thickness of strokes in an etching or the overall formal and technical limits of a medium. And the syntax of a medium can emphasize particular elements like form, texture, tone etc at the cost of others. Crawford argues that even though photography is sometimes seen to be a medium without a syntax - a process that merely reflects the world and is therefore in a direct and 'natural' correspondence with it - in fact each particular photographic process is strictly governed by a syntax. Every detail of the process - the tone, the detail, the reproducibility, even the duration of exposure required or things like generic conventions contribute towards the syntax. Together they define the limits and possibilities of the medium, how it produces the photographic artifact and how we, as the audience, make sense of that artifact. If anything, the photographic process is so intimately tied up with technology that the limits and possibilities of the syntax must be confronted every step of the way.

Thus Crawford sets out to write a history of early photography not as a history of linear events, but as one of the evolution of the photographic syntax. Part I of the book, divided into 12 chapters, traces this evolution in terms of changing conventions, demands and technical challenges that forced nineteenth century photography to constantly develop and evolve. The result is a breathtaking history which makes the twentieth century or even the fast pace of recent change with the emergence of digital seem quite tame by comparison. In doing so, it returns the reader to the sense of awestruck wonder that the practitioners of photography or its first audiences and consumers might have felt. To capture a veritable image of the world on a sheet of paper - as if not made by man but by Nature herself - this is something the magical, awesome quality of which we have lost sight of. We with our oh-so-sophisticated cameras, our 51 point autofocus and our MTF charts - even those of us who think of ourselves as 'traditionalists', use older film cameras and obsess over the zone system and sharpness. All of this is mere trifle compared to the wonder - the very sorcery - of the crude image of Paris rooftops on Niepce's bitumen covered glass. And isn't that why so many try alternative processes? To discover a hint of that magic, the discovery of the new world, the first step on the moon? It is akin to the jaded business traveler ticking off his air miles discovering the struggle that went into man's conquest of flight - from the myth of Icarus to the Wright brothers.

And the syntax is not merely a thing-in-itself - a mere description of the technical boundaries of a process. It lives in and interacts with the world in a way an unilinear perception of 'progress' cannot grasp. Thus the Daguerrotype reigned supreme since its introduction in 1839 for a couple of decades. Technically it was capable of producing results that would satisfy the zone system or sharpness junkie of more than a century later. But there were both socio-cultural and technical demands that its syntax couldn't satisfy. Crawford traces how the more painterly rendering of the Calotype and other processes proved more pleasing to an age for which photography had not been established as a completely unique and independent medium and the reproducibility of negative images proved too strong a technical demand to resist. So the syntax moved on, it evolved, it responded to demands.

It is in conceiving of the history of photography as the history of this dialog between form and content, between demand and response that Crawford's approach is so refreshing and unique. It is full of insightful detail accompanied by vignettes and bits of humor that are all the more charming because they do not quite fit with Crawford's somber academic style. Consider for example, the following revelation: "Subjects in early daguerrotypes frequently sit with one hand supporting the chin. They look like deep thinkers: They were actually concentrating on not moving their heads" (9). Similarly delightful are his observations on the limitations imposed by technique and form on content: for example, the depopulated cityscapes in early long-exposure Calotypes, or how the exposure limitations of certain processes dictated the look of many early street photos. Amusing and astonishing, too, are vignettes about the crisis in egg supply when factories were consuming 60,000 or more eggs per day to coat albumen paper or the fact that there were studios in the 1860s churning out over 1,000 copies from a negative per day! All of this leads to a history of photography down to the period of dominance of the silver gelatin print that is truly novel in approach and eye-opening in detail.

I have spent most of this 'review' on Part I of the book. This isn't unintentional because that is the part I found most compelling. The other two parts constitute a practical guide to some of the major processes and techniques of preservation. They are chock-full of detail and great for anyone wanting to try it out, but there are relatively few illustrations and some of the materials and sources from this 1979 book have obviously fallen out of date. For a pure practical guide, perhaps more recent books like Barnier's or James' might be better, or even one of the many internet sources for quick summaries of processes. But Crawford's basic introduction to sensitometry (while a little advanced in that it tends to assume familiarity with conventional darkroom sensitometry) and technique is very helpful. In other words, buy another book if you want merely a DIY guide, but definitely read this book if you want a perspective that will change the way you look at photography - not only its past, but even its present.

For years (many!) I have been saying the first part of this book is one of the most important texts on history of early photography, and one of the very few that truly follow, in quality and good thinking, the path set by the genious William Ivins Jr.
Ever since the advent of the internet I have tried to find information on the author, and to try to contact him as I intented to translate this text in Keepers to Spanish. Now that I have turned 60 and am both broke and in bad health (and out of work!), I was wondering if I might try to make this dream soemhow come to life ,,,,
If you might be able to perhaps find a way for me to put this idea forward to William Craford himself, I would be very thankful.

Thanks for the comment. I do think it would be wonderful to have this translated. Unfortunately, I don't have Mr. Crawford's contact information. But since he has commented above, perhaps he might see your comment and get in touch.
