Definition and Brief History of Photographs

••Definition and Definition of Photography••
Photography (from English: photography, which comes from the Greek word “Photos”: light and “Grafo”: Painting) is the process of painting / writing using light media.
Photography means the process or method for producing images or photos of an object by recording the reflection of light that hits the object in light sensitive media.
The most popular tool to capture this light is the camera. Without light, no photos can be made.
To produce the right light intensity to produce an image, a measuring aid in the form of a light meter is used.
After getting the right lighting size, a photographer can adjust the intensity of the light by changing the combination of ISO / ASA (ISO Speed), Diaphragm (Aperture), and Shutter Speed ​​(Speed).
The combination of ISO, Diaphragm & Speed ​​is referred to as Exposure. In the era of digital photography where film was not used, the speed of the film that was originally used developed into Digital ISO.

••History of Photography••
History of Photography began in the 19th century. 1839 was the year of the birth of photography.
At that time, in France it was officially stated that photography was a technological breakthrough.
At that time, two-dimensional recordings as seen by the eye could be made permanent.
The history of photography began long before Christ. In the 5th century BC (BC), a man named Mo Ti observed a symptom.
If on the wall of a dark room there is a small hole (pinhole), then on the inside of that space will be reflected in the view outside the space in reverse through the hole. Mo Ti was the first person to realize the phenomenon of the camera obscura.
Centuries later, many realized and admired this phenomenon, say Aristotle in the 3rd century BC and an Arab scientist Ibn Al Haitam (Al Hazen) in the 10th century BC, who tried to create and develop tools that are now known as a camera.
In 1558, an Italian scientist, Giambattista della Porta called “camera obscura” in a box that helped painters capture the image of the image.
The name of the camera obscura was created by Johannes Kepler in 1611.
Johannes Kepler made the design of a portable camera made like a tent, and named the device a camera obscura.
Inside the tent is very dark except a little light captured by the lens, which forms a picture of the situation outside the tent on a piece of paper.
Various studies were carried out beginning in the early 17th century, an Italian scientist – Angelo Sala used sunlight to record a series of words on a silver chloride plate.
But he failed to maintain the image permanently. Around 1800, Thomas Wedgwood, an Englishman experimented to record positive images of lensed camera obscura images, the results were very disappointing.
Humphrey Davy carried out further experiments with silver chloride, but the same fate even though he managed to capture images through a camera obscura without a lens.
Finally, in 1824, a French lithography artist, Joseph-Nicephore Niepce (1765-1833), after eight hours exposed the view from the window of his room, through a process he called Heliogravure (lithograph-like work process) on a metal plate coated with asphalt , managed to give birth to a rather blurry image, managed to maintain the image permanently.
He continued his experiments until 1826, this which eventually became the early history of actual photography. The resulting photo is now stored at the University of Texas at Austin, USA.
Research after research continued until the date of August 19, 1839, the opera stage designer who was also a painter, Louis-Jacques Mande ‘Daguerre (1787-1851) was named the first person to succeed in making a real photo: a permanent image on a copper silver plate sheet coated with iodine solution irradiated for one and a half hours of light directly with a mercury (neon) heater.
This process is called daguerreotype. To make a permanent image, the plate is washed with a salt solution and salt distilled.
January 1839, Daguerre actually wanted to patent his findings. However, the French Government thought that the findings should be distributed to the whole world free of charge.

Photography then developed very quickly. Through the Kodak Eastman company, George Eastman developed photography by creating and selling practical film rolls and box cameras, in line with developments in the world of photography through the improvement of lenses, shutter, film and photo paper.
In 1950, to facilitate the aiming of Single Lens Reflex cameras, prisms (SLRs) began, and Japan began to enter the world of photography with the production of Nikon cameras which were then followed by Canon.
In 1972 Edwin Land’s Polaroid camera was marketed. Polaroid cameras can produce images without going through the process of developing and printing films.
Technological advancements have helped spur photography very quickly.
In the past, a camera the size of a tent can only produce images that are not too sharp, now digital cameras that are only the size of a wallet can make very sharp photos the size of a newspaper.
