What Is Photographic History?

Photographic history is the study of how photography was invented, developed, and transformed from a scientific curiosity into the most pervasive visual medium in human history. In less than 200 years, photography went from requiring hours-long exposures on metal plates to a technology that produces an estimated 1.4 trillion images per year. That trajectory — from Niépce’s blurry view from a window to the camera in your pocket — is one of the most consequential stories in the history of technology and art.

Before the Camera

The basic optical principle behind photography — the camera obscura — was known for centuries. A darkened room with a small hole in one wall projects an inverted image of the outside scene onto the opposite wall. Renaissance artists used camera obscuras as drawing aids. The optics were understood. What was missing was a way to capture the image permanently.

The chemistry came together in the early 19th century. Thomas Wedgwood and Humphry Davy made “sun prints” around 1800 by placing objects on leather treated with silver nitrate. Sunlight darkened the exposed areas, creating silhouettes. The catch: they couldn’t fix the images. Expose them to more light, and the entire surface darkened.

The First Photographs

Joseph Nicéphore Niépce (1765-1833) solved the permanence problem first. Working in France, he coated a pewter plate with bitumen of Judea (a naturally occurring asphalt) and exposed it in a camera obscura. Sunlight hardened the bitumen where it struck; the unexposed portions were washed away. His “View from the Window at Le Gras” (c. 1826-1827), requiring an exposure of several hours (possibly days), is the oldest surviving photograph.

Louis Daguerre (1787-1851) partnered with Niépce and, after Niépce’s death, developed the daguerreotype process. Announced to the world on January 7, 1839 — a date often cited as photography’s birthday — the daguerreotype produced stunningly detailed images on polished silver-coated copper plates. Exposure times started at 15-30 minutes but quickly dropped to under a minute with improved chemistry.

Daguerreotypes were an immediate sensation. Portrait studios opened in cities worldwide. By 1853, the United States alone had an estimated 10,000 daguerreotypists producing roughly three million images per year.

William Henry Fox Talbot (1800-1877), working independently in England, invented the calotype — a process using paper negatives from which multiple positive prints could be made. The daguerreotype produced a single unique image. Talbot’s negative-positive system allowed unlimited copies. This principle — capture a negative, print positives — defined photography until the digital era.

The Wet Plate Era

Frederick Scott Archer introduced the wet collodion process in 1851, combining the sharpness of daguerreotypes with the reproducibility of calotypes. The catch: the photographer had to coat, expose, and develop the plate while the collodion was still wet — a window of about 10-15 minutes. This meant lugging a portable darkroom into the field.

Despite the inconvenience, wet plate photography dominated the 1850s through 1870s. It recorded the American Civil War (Mathew Brady’s team), documented the American West (Carleton Watkins, Timothy O’Sullivan), and made photography accessible enough to spawn the carte de visite craze — small photographic calling cards that Victorians collected and traded.

The Kodak Revolution

George Eastman changed everything. In 1888, he introduced the Kodak camera — a simple box loaded with a 100-exposure roll of flexible film. When you finished the roll, you mailed the entire camera to Kodak’s factory. They developed the film, made prints, reloaded the camera, and sent everything back. The slogan: “You press the button, we do the rest.”

Photography, which had required technical knowledge and expensive equipment, was suddenly accessible to anyone. Eastman didn’t invent the camera. He invented the photography industry — the idea that taking pictures should be easy, cheap, and fun.

The 20th century saw relentless refinement. 35mm film (borrowed from the motion picture industry) became the standard consumer format by the 1930s. Leica’s compact 35mm cameras enabled a new kind of documentary photography — handheld, spontaneous, intimate. Flash photography evolved from dangerous magnesium powder to electronic flash units. Autofocus appeared in the late 1970s.

Color Changes Everything

Color photography’s development was agonizingly slow. James Clerk Maxwell demonstrated the principle in 1861 — combine three photographs taken through red, green, and blue filters — but practical applications took generations.

The Lumière brothers’ Autochrome (1907) was the first widely available color process. Kodachrome (1935) produced vivid, archival-quality color slides and remained the professional standard for over 70 years. But color film was expensive, and many photographers — particularly art and documentary photographers — resisted it. Black-and-white was considered more “serious” well into the 1970s.

Photography as Art

Photography’s relationship to art has been contentious from the start. Painter Paul Delaroche supposedly declared, upon seeing a daguerreotype in 1839, “From today, painting is dead.” He was wrong — painting thrived — but the anxiety was real.

The pictorialist movement (1880s-1920s) fought for photography’s acceptance as art by making photographs look like paintings — soft focus, handworked prints, carefully composed scenes. Alfred Stieglitz championed this cause through his gallery and magazine.

Modernist photographers (Edward Weston, Ansel Adams, Walker Evans) took the opposite approach — sharp focus, pure photographic technique, no manipulation. Photography should look like photography, not painting. Adams’ Zone System gave photographers precise control over exposure and development.

By the late 20th century, photography’s status as a fine art was settled. Major museums collect and exhibit photographs. Fine art prints sell for millions — Andreas Gursky’s “Rhein II” sold for $4.3 million in 2011.

The Digital Revolution

The first digital camera — a Kodak prototype built by Steve Sasson in 1975 — captured a 0.01-megapixel image in 23 seconds and stored it on a cassette tape. Nobody at Kodak quite grasped its significance.

Consumer digital cameras appeared in the mid-1990s. By 2003, digital sales surpassed film. Smartphones, starting with the iPhone in 2007, put cameras in everyone’s pocket. Today, the average person takes more photographs in a year than existed in the entire 19th century.

Photography went from a rare, expensive, skilled activity to the most common form of human documentation in history — a transformation that took less than two centuries and shows no signs of slowing down.

Frequently Asked Questions

Who invented photography?

No single person invented photography — it emerged from multiple inventors working on related problems. Joseph Nicéphore Niépce created the earliest surviving photograph around 1826-1827 using a process he called heliography. Louis Daguerre developed the daguerreotype (announced 1839), the first commercially practical photographic process. William Henry Fox Talbot independently invented the calotype, which introduced the negative-positive process that defined photography for 150 years.

When did color photography become common?

The first color photograph was demonstrated by James Clerk Maxwell in 1861, but practical color photography took decades to develop. Autochrome plates (1907) were the first widely available color process but were expensive and fragile. Kodachrome film (1935) and Agfacolor (1936) made color accessible to professionals. Color didn't surpass black-and-white in consumer photography until the 1970s, about 110 years after the first color image.

When did digital photography overtake film?

Digital cameras became commercially available in the mid-1990s, but film remained dominant until the mid-2000s. The tipping point came around 2003-2004 when digital camera sales surpassed film camera sales. By 2010, film represented less than 5% of the photography market. Kodak, the company most associated with film photography, filed for bankruptcy in 2012. Film has since experienced a modest revival among enthusiasts and artists.
