1935: Kodachrome reinvent colour photography

Invented in 1935 by Leopold Godowsky, Jr., and Leopold Mannes, 2 musicians working with Kodak Research Laboratories.
In the Kodachrome process, the colour was produced differently, not using dyes and startches during exposure but instead with a chemical process during the development stage.
This new technique produced colour transparencies that were usable for both projection and reproduction.
However process was so complicated that users had to send the exposed film to a Kodak laboratory for developing and it was not until 1954 that the company began allowing others to use the process.
In the years that followed Kodak continually developed the film making it improving its exposure speed, processing speed, and of course the quality of image reproduction. All of these factors soon meant that the price came down and Kodak was the No.1 goto for the amatuer photographer

1907: Autochrome introduced
By the 20th century, photography was a relatively simple process that many hobbist and enthusiast could do, but its lack of colour reproductiuon was its biggest drawback. Many methods starting to emerge to colourise images, from artists hand-tinting daguerreotypes and calotypes, but in 1907 the first commercially successful colour photographic process was introduced by The Lumière brothers. Their method, called autochrome, used a glass plate instead of plastic film. The plate was coated with light-sensitive chemicals and granules of dyed potato starch, which acted as a colour filter. The process resulted in a colour transparency (now known as a slide). However, because this was once again a positive image it could only be viewed using a light source, and, like the daguerreotype, it was not easy to reproduce.

In 1900 Kodak launched the Brownie camera, which was sold for just a dollar. It had a roll of film, meaning that you no longer had to send the whole camera for developing.
The Brownie was the founding member of amateur photography.

1888: Kodak brings photography to the general public
From 1888 the American entrepreneur George Eastman’s company, sold the Kodak which contained a 100-exposure roll of paper negatives. Once completed this was sent back to the company to process your photos. “You press the button, we do the rest” was the company’s slogan.
The next year the paper negatives were replaced by plastic film, which had been earlier invented in 1887 by Hannibal Goodwin in Newark, New Jersey.
And the birth of amateur photography happened as photography became available to the masses.

1841: The calotype method
The ability to create multiple positive images came a couple of years later, when the English chemist, William Henry Fox Talbot patented the calotype. Talbot had been experimenting with photography for years, and he continued to perfect his technique whilst the daguerreotype rose in popularity.
In 1841 he had succussfully fixed a negative image on light-sensitized paper that needed much less time to expose. From that image he could create multiple positive images. Although the daguerreotype remained popular, it was the calotype that laid the foundation for modern film photography, in which negatives allow many positives to be printed.

1839: The invention of the daguerreotype
Daguerre built on Niépce’s process, going onto invent the daguerreotype. For this he placed a polished copper plate coated with light-sensitive silver iodide in a lens-fitted camera. After briefly exposing the plate, he treated it with mercury v***r to produce an image and then fixed the image, using a solution of common salt.
The higher quality of the positive image and the shorter exposure times made the daguerreotype process the first widely used photographic method. Although the daguerreotype was a unique image that was difficult to reproduce.

1826: The first photograph made
The first successful attempt to fix an image occurred a few centuries later. In 1826 or 1827 the French inventor Nicéphore Niépce made the first permanent photograph, using a process he called heliography. The method involved applying a light-sensitive solution to a polished metal plate (in this case, bitumen over pewter), placing the plate in a small camera obscura, and then exposingthe plate. For this work Niépce exposed the plate to the sunlit view outside an upstairs window of his country estate, Le Gras, for several days. The result was a black-and-white image of the house’s wings, and the silhouettes of a tree and a chimney in the background.
Niépce acknowledged, however, that heliography needed improvement, and he partnered with Louis-Jacques-Mandé Daguerre, a professional scene painter for the theater, to perfect the process.

11th century AD: The first camera obscura built

The Arab astronomer and mathematician Ibn al-Haythamis is thought to have been the first to build a camera obscura and is often refered to as the father of modern optics.
Based on the phenomenon described by Mozi (see previous post), the camera obscura comprises of a dark box with a hole or lens in one wall which projects on the opposite wall an inverted image of the view.
For centuries the camera obscura was used for viewing eclipses of the Sun without endangering the eyes.
Portable versions were later built, followed by smaller models which by the 16th century, was considered an aid to drawing.

About 400 bc: The concept of photography discovered or at least the physics of projecting an image, using light.
The earliest account of the phenomenon was by the Chinese philosopher Mozi around 400 bc. He observed and documented that when light rays from an object that is illuminated pass through a pinhole into a dark room, they project an inverted image of the object on the opposite wall.
This observation later became the basis for the camera obscura, the modern day camera’s ancestor.
