Baby pictures, graduation pictures, wedding photos, senior portraits, party snapshots, and even cellphone “selfies” all share a common theme – a desire to capture moments that hold personal significance, generally of loved ones, family, friends, and self. This need to record and hold dear memories is not a new one; throughout history, we have attempted to record ourselves and others by the best means available, via cave drawings, hieroglyphics, paintings, sculpture, and in the past 200 years, through photography. While modern cellphone cameras and prolific social media venues have made portrait making and sharing an almost trivial undertaking today, the easy access to portraits of friends, family, and self we enjoy is the result of years of technical and aesthetic development in the field of photography.

While the advancement of photography steadily progressed from daguerreotypes, through calotypes, wet plate collodion, dry gelatin plate, on to celluloid film, one aspect of this progress was a constant – the images obtained were monochromatic or gray scale, exhibiting a tonal response from white through gray to black. All of these methods failed to address a key limitation posed by the silver-based emulsions they all shared. They did not capture the natural world as the human eye perceived it – in color.
As an aspiring photographer in 1850, one would be faced with a choice of two avenues to pursue, the daguerreotype process or Talbot’s calotype process. Daguerre’s process offered extremely detailed positive images, but the limitation of only one-off image production; each image produced was a non-reproducible original. Conversely, the calotype yielded softer, less sharp negative images, but one that could be used repeatedly to make multiple positive copies. The new challenge then was to combine the strengths of these two processes while eliminating their shortfalls.
This was the dilemma facing Englishman Frederick Scott Archer (1814-1857), a sculptor who had been using calotype portraits to facilitate his sculptural work. Archer realized the limitations imposed by paper as a carrier for the light-sensitive emulsion; even papers made translucent by waxing still softened the captured image, and transmitted the paper’s textures to the image. Archer realized that a better carrier for the emulsion would be glass, but the light-sensitive chemicals would not adhere directly to glass; a binding agent, obviously clear, was required.

Shortly after Louis Daguerre presented the results of his pioneering photographic work to the world in 1839, the daguerreotype appeared to stand alone as a unique technological achievement. It seemed to address the primary concerns of the photographic experimenters of the time; to capture real-world images using a relatively short exposure time; to yield an image of acceptable resolution and aesthetic value; and to create an image demonstrating a fade-free permanence. That the daguerreotype did all this so well, with no legal or patent restrictions on the practitioner, it was no wonder that the process quickly found a near fanatical following throughout the world.
Before the formal unveiling of Daguerre’s achievements in August 1839, word had begun to spread throughout Europe that the Frenchman had succeeded in developing an innovative method of recording camera images. These rumors prompted an English scientist and mathematician, William Henry Fox Talbot (1800-1877), to hurriedly present the details of his independently developed process to the Royal Society in January and February 1839. Unaware of each other’s efforts, both Daguerre and Talbot had been simultaneously working to solve the early riddles of photography. While it turned out that each man had taken decidedly different technical approaches to the problem, Talbot had naturally assumed that Daguerre’s method mirrored his own, and he was attempting to establish a claim to priority.
As noted in Part 1 of this series, Joseph Niepce is generally acknowledged as the first successful photographer, through his achievement in 1827 of capturing, via his heliography process, an image that remained light-fast (did not continue to darken when further exposed to light). This process was limited by the extremely long exposure time required by the materials involved. Shortly after this achievement, he was introduced to French artist and businessman Louis Jacques Mande Daguerre (1787-1851) through their optician, Charles Louis Chevalier, who manufactured the lenses for their cameras obscura. Together they strove to improve the process Niepce had fathered. Continue reading “A Brief History of Photography: Part 2 – Daguerre”
