The Evolution of Photography: With a Chronological Record of Discoveries, Inventions, Etc., Contributions to Photographic Literature, and Personal Reminescences Extending over Forty Years

In Short

John Werge offers a personal, chronological account of photography’s first forty years, tracking its rapid evolution from early chemical experiments to widespread commercial adoption. Writing as an active practitioner, Werge blends technical history with personal memoirs, detailing the shift from Daguerreotypes to wet collodion and rapid dry plates. He recounts legal battles over patents, key inventions, studio portraiture, and adventurous field expeditions to places like Niagara Falls. The book remains vital because it provides an authentic, eyewitness bridge between the art's raw beginnings and its establishment as a modern visual medium.

The Story

The narrative begins with the initial chemical discoveries that made capturing light possible. Werge highlights early experiments with silver salts and organic accelerators like gallic acid, which drastically reduced exposure times. He documents the fierce intellectual property struggles of the early period, notably the high-stakes trial Talbot versus Laroche, where the legal limits of early photographic patents were tested and ultimately broken, opening the medium to wider public experimentation.

Werge then traces his own entry into the trade during the late 1840s. He recounts gilded Daguerreotypes, working alongside pioneers like George Brown, and setting up glass-house studios. As the industry matures, the narrative follows the rapid replacement of the Daguerreotype by the wet collodion process. Werge details his work in Glasgow, capturing portraits of prominent historians, engineers, and artists, and even selling prints to royalty. His narrative illustrates how studio portraiture transformed photography from an obscure novelty into a booming commercial enterprise.

Beyond the studio, the text highlights the physical challenges faced by early photographers. Werge shares his adventurous travels in North America, navigating the waters of Lake Ontario, exploring cities like Albany and New York, and risking life and limb alongside fellow pioneers to photograph Niagara Falls. He describes carrying heavy, cumbersome gear to dangerous precipices, cutting down tree branches over cliffs, and exposing negatives in unpredictable wilderness conditions.

The final section chronicles the eventual victory of gelatine-bromide dry plates over wet collodion. Werge records his efforts to persuade skeptical studio owners—such as Messrs. Elliott and Fry—to adopt rapid dry plates, demonstrating that exposure times could be slashed from ninety seconds to a fraction of that duration. The book concludes with a comprehensive chronological index of patents, optical advances like wide-angle lenses, and memorials to late pioneers, offering a complete historical record of photography's rise to dominance.

How It Unfolds

The dawn of chemical acceleration Early experimenters discover that applying gallic acid to light-sensitive paper drastically reduces exposure times. Sir John Herschel and other contemporary scientists marvel at the sharp shadow details produced by these weak chemical solutions.

Breaking the patent monopolies Legal battles come to a head in the trial of Talbot versus Laroche. The testimony reveals prior artistic knowledge, dismantling strict patent monopolies and allowing photographers across Britain to practice their craft freely.

Establishing the commercial studio Werge enters the profession by mastering Daguerreotypes, partnering with experienced operators, and opening portrait studios in Glasgow. He photographs leading figures of science, engineering, and art, while navigating early studio technology.

Expeditions into the American wilderness Taking the camera out of the studio, Werge travels across the United States and Canada. He details the hazardous labor of photographing Niagara Falls from precarious rock ledges and describes the vibrant commercial photo galleries of New York City.

The triumph of the dry plate The wet collodion process yields to rapid gelatine dry plates. Werge demonstrates the superior speed of these new plates to skeptical studio veterans, cementing a technological revolution that makes modern snapshot photography possible.

The People

• John Werge: The narrator, author, and photographic practitioner. Driven by a desire to document the growth of his profession, he works for over forty years across Britain and North America, advocating for new techniques while building a successful portrait business.
• Sylvester Laroche: An artist and photographer who stands up against restrictive photographic patents. He wins a landmark legal fight for professional freedom but suffers severe financial loss, ending his life as a revered martyr of the photographic movement.
• George Brown: An experienced London studio operator who builds the first glass-house studio in Werge's native town. He acts as Werge's early mentor and lifelong friend, sharing vital practical knowledge of the Daguerreotype.
• Sir John Herschel: A prominent scientist whose correspondence and validation of early chemical acceleration techniques lend scientific credibility to nascent photographic processes.
• William Henry Fox Talbot: A leading inventor of paper photography whose attempts to control key chemical accelerators through legal enforcement are challenged in court.

In Its Own Voice

"There was just a passing glimpse of outline, 'and in a moment all was dark.' It was evident, however, that I was in possession of all, and more than all, I wanted, and that the dilution of so powerful an accelerator would probably give successful results."

Werge quotes an early experimenter describing the intense excitement of watching a light-sensitive sheet react to gallic acid.

"I had the good fortune to retain the best of Mr. Hughes's customers, and make new ones of my own, as well as many staunch and valuable friends, both among what I may term laymen and brother Masons, while I resided in Glasgow."

Werge reflects on his prosperous years running a high-end commercial portrait studio in Scotland.

"From the ashes of this burning shame Photography arose, Phoenix-like, and with Silver, seven times purified, took her ethereal form into the hearts and ateliers of artists..."

Werge describes how the medium transcended early legal and commercial squabbles to form a lasting partnership with fine art.

What It's Really About

The book explores how technological innovation, intellectual property disputes, and individual perseverance intersect to shape a new medium. Werge argues that photography's rapid evolution was driven not by isolated geniuses, but by a collaborative network of restless amateurs, practical trade operators, and courageous inventors. The text addresses the tension between monopolistic patents and open scientific progress, showing how the removal of legal barriers sparked rapid growth. Beyond mechanics, it examines the artistic integration of photography, demonstrating how light, chemistry, and optical precision transformed a scientific curiosity into a respected visual art form that captured human history.

Why Read It Today

Readers interested in the history of technology, visual media, and Victorian innovation will find this book a primary source of exceptional clarity. Werge writes with straightforward candor, avoiding dry academic prose in favor of vivid personal anecdotes. Reading his narrative feels like sitting down with a veteran craftsman who lived through every major transition of his trade.

The text carries the natural quirks of late nineteenth-century technical writing, including detailed lists of lens dimensions, commercial prices, and specific chemical formulations. At times, the detailed records of long-forgotten society meetings or optical patents require patient skimming. However, these technical details are balanced by lively travel accounts through North America and humorous descriptions of studio sitters. What lingers long after reading is Werge’s infectious enthusiasm for his craft and his deep respect for the brave experimenters who risked their livelihoods to give the world a new way of seeing.
