A brief history of photography

Photography is from the word photos meaning light, and a co-word graphien that means to draw. This word was first used in 1839 by Sir John Herschel. The concept of photography was formed in about 1000AD when the very first

The concept of photography was formed in about 1000AD when the very first pin-hole camera was created by Alhazen. This became well known as the Camera Obscura which is the literal translation of ‘dark room’ in the Latin language. This camera was a dark box with a small hole or lens that allowed light rays from an object go through it. It had a plate or film inside where the images were produced. It was a major invention. It only had images generated upside down.

Mainly used for viewing and drawing, Camera Obscura was used to record its first photographic image only in 1827 by Joseph Niepce. The image was called heliographs since it was prints of the sun. However, it required eight hours of light exposure to form a picture that did not last since it soon went away.

This invention was later enhanced by Louis Daguerre who had the objective of reducing exposure time. He also tried to prevent the images from disappearing. He named this method daguerreotype.

With time in 1841, another process was formulated by Henry Talbot. It was a negative process that he  named Calotype. It had a black background with its subject in shades of grey.

Later in 1851, the wet plate negative was invented by Frederick Archer. Even though this invention produced a more stable as well as detailed negative, it had a disadvantage which was the need for a darkroom anytime a picture was to be taken to allow development before the emulsion dries.

This invention grew into tintypes which were created by Hamilton Smith in 1856. This version gave a lighter shade than what the calotype produced. By 1879, there came the invention of dry plates, which brought the possibility of a hand-held camera.

George Eastman in 1889 invented the flexible roll film. Colored films were introduced to the market only in the 1940’s.

These innovations defined the future of photography. It has led to the creation of image prints as well as the discovery of many modern photographic devices.

Discoveries that changed the face of photography

Sophisticated techniques came into gradual discovery from the year 1840. Procedures were improved and there was the gradual shortening of exposure time.

Photography has evolved into a separate, thriving field in the arts. The photography field had important leaps  from time to time starting from using the black and white cameras to using the Polaroid cameras that produced pictures in an instant. This has helped the field grow from being used only in portraits to becoming an important tool in the media.

 

Digital Photography

Digital photography is the recent technology that entered the invention scene and made the photography process much easier than what it was before. The digital process has no need for films and darkroom picture development. Images are now captured on a camera sensor (CMOS) and can now be stored in a computer and printed the same way  any other file in the computer would be printed.
