The Evolution Of Fluke Cameras: A Historical Perspective

The history of the camera is a long and fascinating one, dating back to the camera obscura, a natural optical phenomenon where an inverted image is projected through a small aperture. This concept evolved over centuries, leading to the development of photographic cameras in the 18th and 19th centuries. The first permanent photograph captured by a camera was made in 1826 by Joseph Nicéphore Niépce, using an exposure time of around 8 hours. The introduction of digital cameras in the 1990s revolutionized photography once again, and today, cameras are ubiquitous, found in smartphones and other mobile devices.

The first permanent photograph

Niépce was motivated by the growing demand for affordable pictures and began experimenting with photography in 1816. He conducted his photographic experiments with the dual aims of copying prints and recording scenes from real life using a camera. Initially, he produced legible but fleeting camera pictures, which he called "points de vue". Over the next decade, he experimented with various chemicals, materials, and techniques to advance the process, which he ultimately called "héliographie", or "sun writing".

To create the first permanent photograph, Niépce dissolved light-sensitive bitumen in oil of lavender and applied a thin coating to a polished pewter plate. He then inserted the plate into a camera obscura and positioned it near a window in his workroom. After an exposure of about eight hours, the plate yielded an impression of the courtyard, outbuildings, and trees outside.

In 1829, Niépce formed a partnership with Louis-Jacques-Mandé Daguerre, and together they continued to improve the heliographic process. However, Niépce died in 1833, before the process was successfully commercialised. Daguerre introduced his "Daguerreotype" process in 1839, which required shorter exposure times and produced clearer, more detailed results.

The camera obscura

In the 11th century, Arab physicist Ibn al-Haytham (known as Alhazen in the West) extensively studied the camera obscura and provided the first experimental and mathematical analysis of the phenomenon. He understood the relationship between the focal point and the pinhole.

Italian polymath, Giambattista della Porta, described the camera obscura in his 1558 book, 'Magia Naturalis', and compared the human eye to the device. In the 17th century, the camera obscura was used by artists such as Canaletto and Rembrandt, and possibly by Johannes Vermeer, to capture scenes with incredible detail.

In the 1800s, the camera obscura was combined with light-sensitive materials, leading to the birth of photography. The earliest known photograph, 'View from the Window at Le Gras', was taken by Joseph Niépce using a camera obscura and a plate coated with chemicals.

Early photographic cameras

The history of early photographic cameras is a fascinating one, dating back to the early 19th century. Let's delve into the evolution of these cameras and explore their impact on the world of photography.

The Birth of Photography

The concept of photography has existed for centuries, with the basic idea tracing back to the 5th century BCE. However, it wasn't until the 11th century that an Iraqi scientist, Ibn al-Haytham, developed the camera obscura, marking the birth of this art form. While the camera obscura projected images, it did not capture them. The images were also upside down, but they could be traced to create accurate drawings.

Early Experiments

In the early 1800s, French inventor Joseph Nicéphore Niépce created a prototype of a photographic camera. Using a portable camera obscura, he exposed a pewter plate coated with bitumen to light, creating the first image that did not quickly fade. This led to various experiments, and photography progressed rapidly.

Daguerreotypes and Calotypes

Niépce's work culminated in a collaboration with Louis Jacques Mandé Daguerre, resulting in the creation of the daguerreotype in 1837. This process involved coating a copper plate with silver and exposing it to iodine vapour before capturing an image. However, long exposure times of up to 15 minutes were required. Daguerreotypes were popular until the late 1850s when they were replaced by emulsion plates.

Around the same time, English scientist William Henry Fox Talbot invented the calotype process, which used negative printing. This process allowed for an unlimited number of positive prints from the original negative and introduced the ability to alter the resulting image through retouching.

Wet Plates and Dry Plates

Emulsion plates, also known as wet plates, were used from the 1830s to the 1870s. They were more affordable than daguerreotypes and required shorter exposure times, making them ideal for portrait photography. However, the wet plate process was superseded by Richard Maddox's invention of dry plate photography in 1871, which offered similar speed and quality but with added functionality.

Roll Film Revolution

The dawn of roll film is closely associated with George Eastman, who founded the Eastman Dry Plate Company in 1881, later renamed Eastman Kodak Company. In 1888, Eastman introduced a flexible roll film, eliminating the need for constantly changing solid plates. This innovation led to the development of self-contained box cameras, making photography more accessible.

Instant Photography

The Polaroid camera, introduced in 1948, revolutionised the industry with its ability to develop instant photographs in under a minute. Despite a decline due to the rise of digital photography, Polaroid cameras have made a comeback, with the company preserving vintage models and introducing new generations.

In summary, the evolution of early photographic cameras spanned from the camera obscura to the introduction of roll film and instant photography. These advancements laid the foundation for modern photography, shaping the way we capture and share images today.

Daguerreotypes and calotypes

The daguerreotype was the first publicly available photographic process, introduced worldwide in 1839. Invented by Louis Daguerre, the daguerreotype was widely used during the 1840s and 1850s. The process involves treating a silver-plated sheet of copper with iodine vapour to give it a coating of light-sensitive silver iodide. After exposure in the camera, the image is developed by mercury vapour and fixed with a strong solution of ordinary salt (sodium chloride). The daguerreotype produces a highly detailed image on a sheet of copper plated with a thin coat of silver without the use of a negative.

The calotype, also known as the talbotype, was an early photographic process introduced in 1841 by William Henry Fox Talbot. Talbot's process used paper coated with silver iodide or silver chloride, which was exposed to light in a camera obscura. The calotype process was the first to utilise negative printing, which reverses all values in the reproduction process – black shows up as white and vice versa. Talbot patented his process in 1841.

The first digital cameras

The first true digital camera was the Fuji DS-1P, released in 1988. It recorded images onto a 2MB SRAM memory card, which used a battery to preserve data. However, this camera was never marketed to the public.

The first portable digital camera to be sold commercially was the Fuji DS-X, released in Japan in December 1989. The first digital camera to be sold in the US was the Dycam Model 1, which was shipped in November 1990. It was a commercial failure due to its high price tag and low resolution, but later saw modest success when rebranded as the Logitech Fotoman in 1992.

The first camera to feature a liquid crystal display on the back was the Casio QV-10, developed by a team led by Hiroyuki Suetaka in 1995. The first camera to use CompactFlash was the Kodak DC-25 in 1996. The first camera phone was the Kyocera Visual Phone VP-210, released in Japan in May 1999.
