The Development of Paper Photography

In the late 1830s, the emergence of photography was defined by two distinct technical philosophies. While Louis Daguerre in France championed a method that fixed sharp, singular images onto polished silver-plated copper sheets, William Henry Fox Talbot in Britain pursued a radically different medium: paper. Talbot had grown frustrated during a trip to Lake Como in Italy, where his attempts to sketch landscapes using a camera lucida produced disappointing results. Determined to make nature record its own outlines automatically, he began experimenting with light-sensitive chemicals brushed directly onto writing paper. By coating sheets in a weak solution of common salt and subsequently floating them on silver nitrate, he created silver chloride within the paper fibres. When pressed against flat objects such as leaves or lace and exposed to sunlight, these prepared sheets darkened where light struck them, leaving a white silhouette. Talbot termed these initial creations ‘photogenic drawings’.

Although photogenic drawing proved effective for contact printing flat botanical specimens, it required impractical exposure times—often up to an hour—when placed inside a camera obscura to capture three-dimensional scenes. In 1840, Talbot made a crucial discovery that transformed the efficiency of his technique: the concept of the latent image. He realised that an invisible image formed on the paper after only a few seconds of exposure, which could subsequently be brought out using a chemical developer. By treating the paper with gallo-nitrate of silver—a combination of gallic acid and silver nitrate—exposure times fell dramatically from sixty minutes to less than three minutes. Patented in 1841 as the ‘calotype’ (from the Greek kalos, meaning beautiful), this innovation also introduced the fundamental photographic principle of negative-to-positive reproduction, allowing multiple prints to be generated from a single master paper negative.

The visual quality of the calotype stood in sharp contrast to the precise, metallic mirror of the daguerreotype. Because light had to pass through the fibrous structure of the paper negative when making a positive print, the resulting images displayed a softened, textured appearance with broad tonal gradations reminiscent of charcoal drawings or mezzotints. While scientists and commercial portraitists frequently criticised this lack of microscopic sharpness, painters and artistic practitioners embraced it. In Scotland, the pioneering partnership of the painter David Octavius Hill and the engineer Robert Adamson exploited this characteristic to remarkable effect. Producing roughly three thousand calotypes in the fishing village of Newhaven and around Edinburgh between 1843 and 1847, they captured the rugged faces of local fisherfolk and community elders, establishing paper photography as a legitimate fine art.

Concurrently, other experimenters sought alternative chemical bases for paper imagery. In 1842, the astronomer and polymath Sir John Herschel devised a process that bypassed silver salts entirely, relying instead on light-sensitive iron compounds. By coating paper with a mixture of ferric ammonium citrate and potassium ferricyanide and washing it in plain water after exposure, he produced vivid Prussian blue prints known as cyanotypes. Herschel initially intended the method for copying mathematical tables and astronomical charts, but it soon found an unexpected practical application. The botanist Anna Atkins utilised the cyanotype to assemble British Algae: Cyanotype Impressions, widely regarded as the first book illustrated with photographs. The rich blue background provided exceptional contrast for the delicate contours of dried seaweeds, demonstrating the viability of iron-based printing.

Despite its creative advantages, early paper photography suffered from practical limitations, notably the fragility and graininess of ordinary paper negatives. In 1851, the French photographer Gustave Le Grey introduced a significant refinement known as the waxed paper process. By saturating the dry paper with molten beeswax prior to sensitising it with chemicals, Le Grey rendered the base translucent and dramatically reduced the visibility of internal fibres. Crucially, while standard calotype paper had to be sensitised immediately before exposure and developed shortly afterwards, waxed paper could be prepared several days in advance and developed weeks later. This stability made the technique exceptionally popular among travelling photographers documenting distant architecture and landscapes across Egypt, India, and southern Europe.

However, the broader adoption of the calotype in England was severely constrained by legal barriers. Talbot vigorously defended his 1841 patent, demanding substantial licensing fees from anyone attempting to practise the method commercially. This aggressive stance alienated many amateur enthusiasts and stifled commercial studios across London. By contrast, in France, where the state had purchased Daguerre’s invention and made it freely available to the public, photographic societies flourished. The legal dispute in Britain culminated in an 1854 court case, Talbot v. Laroche, in which the court ruled that newer photographic variations did not infringe Talbot’s original patent. Although Talbot relinquished his remaining claims shortly thereafter, the legal battles had already dampened British momentum.

By the mid-1850s, the paper negative was rapidly superseded by Frederick Scott Archer’s wet collodion process, which utilised glass plates to achieve both the transparency needed for sharp detail and the reproducibility of a negative. Nonetheless, the legacy of paper photography endured. While glass became the standard support for negatives, paper remained the undisputed foundation for positive prints. Millions of albumen prints—paper coated with egg whites to hold silver salts on a glossy surface—were produced from glass negatives during the second half of the nineteenth century, cementing the negative-positive paradigm that Talbot had established.
