Camera Obscura
Many people believed photography began during 1822, however it actually dates back to over 400BC, where the camera obscura technique was used. Camera obscura is a lightproof box or room with a hole in one side. Light from the sun then reflects off objects outside the camera obscura and passes through the hole, lighting up the surfaces inside the room with an inverted projection of the outside view. Since the renaissance period many Artists would manually trace what they saw, or use the optical image as a basis for solving the problems of perspective and parallax, and deciding colour values. This method became the first way to make an image.
Nicephore Niepce
Thousands of years later a man named Nicéphore Niépce was born. Niépce grew up to be a French inventor and one of the earliest pioneers for photography. Within his lifetime he took the first ever photograph during 1826, he did so using his Heliography technique. Niépce created the heliograph by dissolving light-sensitive bitumen in lavender oil and lightly covering a polished pewter plate with it. He placed the plate next to a window in his second-story workroom and put it into a camera obscura which then created the photo.
This photo inspired many other photographers to experiment with this technique and to explore the potential of the medium. Niépce’s photo opened the door to a new form of art and expression, and it paved the way for the development of modern photography.
Louis Daguerre and Daguerreotype
Another impactful figure in the history of photography is Louis Daguerre, a French artist and photographer who eventually became one of the fathers of photography.
Using a thin copper sheet coated in silver and subjected to the vapour released by iodine crystals, Daguerre created a layer of light-sensitive silver iodide on the surface of the technique that would later be called the daguerreotype. In the camera, the plate was then exposed. To make a distinct image, this procedure initially also needed a very long exposure. However, Daguerre made the important discovery that a much shorter exposure could produce an invisible dim “latent” image that could be chemically “developed” into a visible image. After viewing the image that he created he said “I have seized the light – I have arrested its flight!” The daguerreotype process allowed people to capture the image created using camera obscure and preserve it as an object. It became the first practical way to take a photograph and ushered in a new age of pictorial possibilities. The invention of daguerreotype was announced to the public during 1839 in a meeting of the French Academy of Sciences in Paris.
Henry Fox Talbot
Another father of photography is Henry Fox Talbot, who has been credited the British Inventor of Photography. In 1834 Talbot discovered how to make and fix images through the action of light and chemistry onto paper. These ‘negatives’ could be used to make multiple prints and this process revolutionised photography. Talbot patented his invention of this process, and named it ‘Calotype’ during 1841. The process of the Calotype has influenced photographic technologies which are still used today. His interests in photography developed beyond his initial discovery as he also pioneered photographically illustrated books and photomechanical reproduction methods, this led the way to the ‘age of the image’.
These leaves are images which Talbot took, the lighter leaf is the negative image and the darker leaf is the positive image after it had been developed.
Richard Maddox
Richard Leach Maddox, was an extremely impactful figure for the invention of the camera. He was an English photographer as well as physician. In 1871 he invented the lightweight gelatine negative plates used for photography, known as dry plates.
A dry plate is a glass plate coated with a gelatine emulsion of silver bromide and it is able to be stored until exposure. After the dry plate has been exposed it can be brought back to the darkroom for development at leisure. Dry plates were able to be bought in stores which allowed photographers to create photos without having to prepare their own dry plates. Negatives did not need to be developed immediately and for the first time, cameras could be small enough to be hand-held. Cameras could also be concealed, and with further research fast exposure times were created which led to snapshot photography, as well as the Kodak camera and roll film, this paved the way for cinematography. The John Scott Medal was rewarded to Maddox during 1889 and the Royal Photographic Society’s silver medal in 1901.
George Eastman
These dry plates were created by an entrepreneur, philanthropist, and the pioneer of popular photography and motion picture film, George Eastman. When travelling Eastman found that the weight, the awkwardness and the cost of the equipment required to take and develop photographs was a struggle. This led him to seek improvements. After experimenting for three years with gelatine emulsions, by 1880, he had invented and patented a dry-plate coating machine. Eastman formed the Eastman Dry Plate Company in 1881, which led to the development of easy-to-use cameras, this enabled many people to take photographs, and developed a flexible film that was a critical contribution to the launch of the motion picture industry.
Kodak Brownie
Eastman Kodak developed a series of camera models known as the Kodak brownie which were first released during 1900.
The Brownie was a basic cardboard box camera which has a simple conveys-concave lens which took 2 1/4 inch square pictures on number 117 roll film. The Kodak Brownie had an initial price of $1, which is equivalent to around $37 as of 2023, and it had simple controls, the Kodak roll film and processing also had a low price, which is why it surpassed its marketing goal.
Digital Photography
Today, digital photography is used which is a complex technological process which uses optical physics, materials engineering, and data science to transform light into electrical signals which are converted into photo elements, creating a digital image. This was initiated by the American Computer engineer, Russell Kirsch, who during 1957 developed the first rotating drum scanner and software which was able to digitally record images. Just 3 years later in 1960, two engineers George Smith and Willard Boyle developed the charge-coupled device, the precursor to the CMOD, used in fully digital cameras. However the first digital photo camera was not created till 1975 by an engineer working for the Eastman Kodak company named Steve Sasson. Sasson developed him camera using an image sensor created in the previous year. This camera weighed almost 9 pounds and took 23 seconds to capture one photograph.
Conclusion:
Therefore photography originated very early on when the camera obscura was used, however it was not as popular and easily accessed until many years later when the Kodak Brownie was invented as it was an easy way for many people to take their own photos without the need for all of the equipment necessary in earlier years of photography.
