What is Photo and Photography

what is photo and photography

Contrary to what is known, digital photography technology requires more photographic information, although it is not used much now, in addition to everything known for analog photography, we should know the machine you use, digital photography specific information and concepts, shooting techniques, and how to properly process photos on a computer.

For this, we can briefly list for you that the secrets of the What is Photography and Photography discourse are not difficult at all, as in the title. Venue timing, Light, Camera settings, Portrait art for taking portrait, Composition, Flash and the correct use of light, etc. like, a little experience.

Short History of the Photograph:

The exact date of how photography started and where it is located is unknown.

In the eighth century, the Arab origin Jabir Ibn Khayyam found that “Silver Nitrate” was darkened by the effect of sunlight, and in the 15th century Leonardo da Vinci’s finding that a small hole in a dark room reflects images outside the room is an important starting point in the history of photography. Artists interested in photography found the dark box in the Renaissance era. Thus, they obtained an inverted image of the picture on the other surface of the dark box through a small hole through which light entered. In the 18th century, the image was made visible outside of the box by placing a lens on one end of the dark box or bellows and frosted glass on the other.

The basic photography studies that started with Niepce began to develop rapidly when Daugerre merged with the works of Jacques Mande in 1829 and revealed the Daugerreotype in 1837.

In 1840, a lens that passes 16 times more light was used and the exposure time was reduced. Although the image obtained was very clear, the silver-copper plate was easily broken and very expensive, preventing the further development of this technique.

In the same period, even if Henry Fox Talbot succeeded in obtaining a picture on papers treated with some chemical substances, it was forgotten in this method because the picture gradually darkened and the image was not clear. But for this invention of Talbot, the word “PHOTO” was used for the first time in this subject. After a while, it was achieved to turn negative exposure into positive. In this way, the first foundation of modern photography was laid.

At the time of these developments, the longest exposure time achieved to take a photo was 1/25 second.

In 1852, George Eastman introduced Kodak cameras with bromide coated Gelatin roll films that can take 10 shots on Kodak cameras, allowing easy movement for photographers who need to carry very large photographic equipment. After the photo was taken, the camera was sent to the factory, placed on a glass after the gelatin film was separated from the paper, and then returned to its owner by filling the film back into the camera.

In 1870, Hermann Vogel discovered a way to increase the sensitivity of emulsions by immersing them in various chemical baths. In 1880, orthocomatic films with very limited sensitivity to red color were found, as well as panchromatic films. Photography As a result of the use of different and better quality astigmatic lenses and cellulose-based films in the 19th and 20th centuries, the developments in the analog camera and film industry have come to this day, and we are experiencing the incredible beauty of digital technology in our time period.
