History of Photography

Understanding and Definition of Photography

Photography ( from English : photography , which is derived from the Greek word is " Photos " : light and " Grafo " : Painting ) is the process of painting / writing using light media .

Photography means a process or method to produce an image or images of an object by recording the reflection of light on the objects on light sensitive media . The most popular tool for capturing this light is the camera . Without light , there is no photograph that can be made .

To generate proper light intensity to produce an image , use the help of a measuring instrument lightmeter . After obtaining the proper size of the lighting , a photographer can adjust the light intensity by changing the combination of ISO / ASA ( ISO Speed ​​) , diaphragm ( aperture ) and shutter speed ( Speed) . The combination of ISO , Diaphragm & Speed ​​referred to as Exposure ( Exposure ) . In the era of digital photography in which the film is not used , then the speed of the film that was in use evolved into Digital ISO .

history of Photography

History of Photography started in the 19th century . 1839 is the year of the birth of photography . At that time , in France officially declared that photography is a technological breakthrough . At that time , recording two- dimensional as the eye can be made permanent .

History of photography began long before the AD . In the 5th century BCE (BCE ) , a man named Mo Ti observes a phenomenon . If the wall of a dark room there is a small hole ( pinhole ) , then on the inside of the chamber will be reflected in the view of the outside of the room in reverse through the hole . Mo Ti was the first to realize the phenomenon of the camera obscura .

Centuries later , many are aware of and admire this phenomenon , namely Aristotle in the 3rd century BC and an Arab scientist Ibn al Haitam ( Al Hazen ) in the 10th century BC , which seeks to create and develop a tool that is now known as a camera . In 1558 , an Italian scientist , Giambattista della Porta called the " camera obscura " in a box that helps artists capture shadows image .

Name of camera obscura was invented by Johannes Kepler in 1611 . Johannes Kepler makes the camera portable design that is made like a tent , and gave the name of the device camera obscura . Inside the tent was very dark except for a bit of light captured by the lens , the image formed in the state outside of the tent on a piece of paper .

Various studies conducted starting in the early 17th century , the Italian scientist - Angelo Sala use sunlight to record a series of words on a plate of silver chloride . But he failed to maintain a permanent image . Around the year 1800, Thomas Wedgwood , a British experiment to record a positive image of the image in the camera obscura lens , the results are very disappointing . Humphrey Davy conduct further experiments with silver chloride , but also meet the same fate , despite being caught by the camera obscura images without lens .

Finally , in 1824 , a French artist lithography , Joseph - Nicéphore Niepce ( 1765-1833 ) , after eight hours of clicking - exposed view from his bedroom window , through a process called heliogravure ( process works similar lithograph ) on top of a metal plate coated with bitumen , successfully gave birth to a somewhat blurred image , also managed to maintain a permanent image . He continued his experiments until 1826 , is what eventually became the actual early history of photography . The resulting image is now stored at the University of Texas at Austin , USA .

Study after study continues to pata dated dated August 19, 1839 , the opera stage designer who is also a painter , Louis - Jacques Mande ' Daguerre ( 1787-1851 ) was crowned as the first to successfully create photo real : a permanent image on a sheet of copper plate silver coated with a solution of iodine were exposed for one and a half hours of light directly heated mercury ( fluorescent ) . This process is called the daguerreotype . To make the image permanent , washable plates salt solution and distilled asir . January 1839 , Daguerre actually want to patent it . However , the French government thinks that the findings should be shared around the world for free .

Photography then develop very quickly . Eastman Kodak company through , George Eastman developed the photography by creating and selling a roll of film and the camera box is practical , in line with developments in the world of photography through improved lens , shutter , film and photographic paper .

1950, to facilitate shooting on a Single Lens Reflex camera then start to use the prism ( SLR ) , and Japan also began to enter the world of photography with a Nikon camera production was followed by Canon . 1972 Edwin Land Polaroid camera findings began to be marketed . Polaroid camera capable of producing images without going through the process of developing and printing film.
