The Evolution Of Camera Manufacturing Origins

The history of the camera is a long one, dating back to the invention of the camera obscura, a natural optical phenomenon where an inverted image is projected through a small aperture. The earliest explanation of this comes from Han Chinese philosopher Mozi around 470-391 BC.

The first camera was invented in 1816 by French inventor Nicephore Niepce. His simple camera used paper coated with silver chloride, which would produce a negative of the image. However, these images were not permanent. Niepce later experimented with a film made from Bitumen of Judea, a semi-solid form of oil that appears like tar, mixed with pewter, to create permanent images.

The first photographic camera was developed in 1816 by Frenchman Joseph Nicéphore Niépce. In 1826, his prototype was used to take the first photograph ever, which captured the view out of the window of his home in France. This image took Niépce at least eight hours to produce.

The first camera to be mass-marketed was a daguerreotype camera produced by Alphonse Giroux in 1839. It cost 400 francs (approximately $7,000 by today's standards). This consumer camera had an exposure time of 5 to 30 minutes, and users could purchase standardized plates in a range of sizes.

The first camera was the camera obscura, a dark room with a small hole that projected an inverted image of the outside scene

The first camera was the camera obscura, a natural phenomenon where a small hole in a darkened space projects an inverted image of the outside scene. The name is derived from the Latin words "camera" (room) and "obscura" (dark). The earliest written record of the camera obscura dates back to the 4th century BCE, with the first known written account provided by Chinese philosopher Mozi (or Mo-tzu) around 400 BCE. Greek philosopher Aristotle also observed the phenomenon in the same century.

The camera obscura is a simple device consisting of a dark room or box with a small hole in one side or the top. When light from an external scene passes through the hole and strikes a surface inside, it reproduces an inverted and reversed image, with colour and perspective preserved. The image can be projected onto a screen or the wall opposite the hole, and the size of the aperture determines the sharpness and brightness of the image.

Over time, the camera obscura was refined and improved. In the 11th century, Arab physicist Ibn al-Haytham (known as Alhazen in the West) conducted experiments and provided the first correct analysis of the camera obscura. He is often credited with the invention of the pinhole camera and was the first to utilize a screen for image projection. In the 16th century, further technical improvements were made, including the addition of a biconvex lens in the opening and a diaphragm to restrict the aperture, resulting in brighter and sharper images.

The camera obscura became widely known in the 16th century through the writings of Italian polymath Giambattista della Porta, who described its use as a drawing aid. Portable versions of the camera obscura were developed, first as tents and later as boxes, making it a popular tool for artists in the 17th and 18th centuries. The box-type camera obscura served as the basis for the development of photographic cameras in the 19th century, leading to the evolution of modern photography.

The first photographic camera was developed in 1816 by Joseph Nicéphore Niépce

In around 1816, Niépce became interested in the new technique of lithography and began experimenting with ways to use light-sensitive materials to produce images directly onto printing plates or stones. He conducted his early experiments using a camera obscura, a precursor to the photographic camera, which projects an inverted image of a scene through a small aperture onto a surface.

Niépce's first experiments involved placing sheets of silver salts-coated paper at the back of a camera obscura, as this material was known to blacken with daylight. In May 1816, he produced the first image of nature: a view from a window. However, this image was a negative, and it vanished as the coated paper became completely black when exposed to broad daylight.

To create positive images, Niépce turned to compounds that were bleached by light instead of blackened, such as salts, iron oxide, and manganese black oxide. While he obtained some results, he encountered a fixing problem, as the initial chemical that had not been transformed by light would be eliminated.

Niépce continued his experiments and eventually developed heliography, a technique he used to create the world's oldest surviving products of a photographic process. He dissolved light-sensitive bitumen in oil of lavender and applied a thin coating to a polished pewter plate. After several days of exposure to sunlight, the plate yielded an impression of the view outside his window, including the courtyard, outbuildings, and trees. This image, created in 1826 or 1827, is now preserved as part of the Gernsheim Collection at the University of Texas and is considered the earliest surviving photograph produced with the aid of a camera obscura.

Niépce's work laid the foundation for modern photography, and he is recognized as one of the earliest pioneers of this art form.

The first permanent photograph was taken in 1826 by Niépce

The world's first permanent photograph was taken in 1826 by Joseph Nicéphore Niépce, a French inventor and one of the earliest pioneers of photography. The image, titled "View from the Window at Le Gras", was captured using a camera obscura and a pewter plate coated with Bitumen of Judea, a type of natural asphalt. Niépce's country estate near Chalon-sur-Saône, France, served as the backdrop for this historic achievement.

Niépce's journey to creating the first permanent photograph began with his interest in lithography and the camera obscura. He recognized his lack of artistic skill and sought to capture the fleeting images produced by the camera obscura. Niépce experimented with various substances and techniques, eventually focusing on Bitumen of Judea due to its light-sensitive properties. He coated a pewter plate with this substance and placed it inside a camera obscura, exposing it to light for several days.

The resulting image, "View from the Window at Le Gras", depicted the view from the window of his upper-story workroom. It included the outbuildings, trees, and landscape of his country house, Le Gras. This photograph marked a turning point in the history of photography and is considered the birth of photography as we know it today. The original plate has been preserved and is now on display at the Harry Ransom Center in Austin, Texas.

Niépce's innovation in photography continued with his development of heliography, a technique he used to create the world's oldest surviving products of a photographic process. Heliography, or 'sun writing', involved dissolving light-sensitive bitumen in oil of lavender and applying it to a polished pewter plate. This plate was then inserted into a camera obscura, capturing an image after several days of exposure to sunlight.

Niépce's contributions to photography were not widely recognized during his lifetime. However, through the efforts of historians like Helmut and Alison Gernsheim, his role as the inventor of photography has been reaffirmed. Today, Niépce is remembered as a pioneer who laid the foundation for the art and science of photography, revolutionizing our ability to capture and preserve visual reality.

The daguerreotype camera was invented in 1839 by Louis Daguerre

In 1829, Daguerre partnered with Joseph-Nicephore Niépce, an inventor who had produced the world's first heliograph in 1822 and the oldest surviving camera photograph in 1826 or 1827. Together, they worked to develop a method to permanently capture the fleeting images visible in a camera obscura. Niépce died suddenly in 1833, but Daguerre continued experimenting and finally achieved success around 1834. The daguerreotype process used a polished sheet of silver-plated copper, treated with iodine to make it light-sensitive. This was exposed for several minutes or more under a lens and then fixed using mercury vapour.

The existence of the process was first announced to the public in January 1839. Recognising the enormous potential of this invention, the French government made a deal with Daguerre, acquiring the rights to the process in exchange for lifetime pensions for Daguerre and Niépce's son. On 19 August 1839, the details of the new daguerreotype process were presented to the public as a gift from France to the world.

The daguerreotype process produces a highly detailed, unique object and is a direct-positive process, meaning no negative is made. To make a daguerreotype, a sheet of copper is plated with a thin coat of silver. This plate is then cleaned and polished to a mirror finish. Next, it is sensitised in a light-tight box with iodine and bromine vapours until its surface turns yellow. The reaction between the iodine vapour and the silver coating produces light-sensitive silver iodide. Once sensitised, the plate is kept in a lightproof container and inserted directly into a camera, where the exposure is made.

Development is then accomplished by placing the exposed plate over a source of heated mercury fumes until the image appears. The image is fixed by immersing the plate in a solution of sodium chloride or salt, and then toned with gold chloride. Exposure times for early daguerreotypes ranged from three to fifteen minutes, but improvements to lenses and the introduction of bromine reduced this to about one minute.

Daguerreotypes were usually portraits, but landscape views and other unusual subjects were also captured and are now sought after by collectors. The images are often laterally reversed, as they are necessarily viewed from the side that originally faced the camera lens.

The first mass-produced camera was the Kodak No. 1, released in 1889

The Kodak No. 1 was a box camera with a fixed-focus lens on the front and no viewfinder. It was loaded with a 100-exposure roll of film that used paper negatives to take circular pictures, each roughly 2.5 inches (65mm) in diameter. The camera was sold for $$25, a high price at the time, and came with a leather carrying case. The camera was loaded at the factory, and after the last negative was exposed, consumers sent the entire camera back to the factory, where the film was processed and reloaded. The camera was then returned to the customer with prints and a new roll of film.

The Kodak No. 1 featured an easily removable lens board and an improved sector shutter, which was set by pulling a string and tripped by pressing a button on the side. The film was then wound to the next frame using a key on the top of the camera. The original Kodak and the No. 1 had a 'V' shape impressed in the leather on the top, showing the angle of view and aiding the user in aiming the camera.

The Kodak camera revolutionised photography, making it accessible to millions of casual amateurs. Eastman's marketing strategy, with the slogan "You press the button, we do the rest", positioned photography as a fun and easy activity for anyone. Within a few years of its introduction, snapshot photography became a national craze, with various forms of the word "Kodak" entering common American speech.
