Photography (from English: photography, which comes 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 reflections about these objects on light sensitive media. The most popular tool for capturing this light is the camera. Without light, there are no images that can be made.
To generate the appropriate light intensity to produce an image, use the help of a measuring instrument in the form of lightmeter. After obtaining a measure of proper 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 and speed is referred to as Exposure (Exposure). In the era of digital photography where the film is not used, then the film speed that was in use evolved into Digital ISO.
History of Photography
Photographic history began in the 19th century. 1839 is the year of the beginning of the birth of photography. At that time, in France declared officially that photography is a technological breakthrough. At that time, recording a two-dimensional as the eye can be made permanent.
History of photography began long before AD. In the 5th century BCE (BCE), a man named Mo Ti observing a phenomenon. If the walls of a dark room there is a small hole (pinhole), then on the inside of the space will be reflected in the view of the outdoors 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 a scientist Arab Ibn Al Haitam (Al Hazen) in the 10th century BC, which seeks to create and develop tools that are now known as the camera. In 1558, an Italian scientist, Giambattista della Porta called the "camera obscura" in a box that helps the painter captures the shadow image.
Name of the camera obscura was created by Johannes Kepler in 1611. Johannes Kepler makes the camera portable design that made such a tent, and give 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 forming state outside the tent on a piece of paper.
Demy research studies continue until pata dated August 19, 1839, the opera stage designer who is also a painter, Louis-Jacques Mande 'Daguerre (1787-1851) was named the first person to successfully make the actual photo: a permanent image on the 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 daguerreotype. To make the image permanent, the plate is washed solution of common salt and distilled Asir. January 1839, Daguerre had wanted to patent it. However, the French Government thinks that the findings should be shared around the world for free.
Photography then developed very quickly. Through the company Eastman Kodak, George Eastman developed the photography by creating and selling a roll of film and camera box that 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 began to enter the world of photography with Nikon camera production was followed by Canon. 1972 Polaroid findings of Edwin Land began to be marketed. Polaroid camera capable of producing images without going through the process of developing and printing the film.
Advances in technology helped trigger the photography is very fast. If the first camera of the tent can only produce an image that is not too sharp, is now the only digital camera for purse able to make very sharp images in the size of a newspaper.

artists of the 19th century used the camera obscura to sketch

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 the image permanently. Around 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 experimented further with silver chloride, but fared equally well, despite being captured images through a camera obscura without lens.
Finally, in 1824, an artist lithography of France, Joseph-Nicéphore Niepce (1765-1833), after eight hours of clicking exposed view from his bedroom window, through a process called Heliogravure (process works similar to lithograph) on a metal plate coated with bitumen , successfully delivered a rather blurred picture, managed to also maintain the image permanently. He continued experimenting until 1826, is what ultimately becomes an actual early history of photography. The resulting image is now stored at the University of Texas at Austin, USA.
