History of photography 2

The British *William Fox Talbot, who already carried out research with photosensitive papers, upon learning of Daguerre's advances, in 1839, decided to hasten the presentation of his works to the Royal Institution and the Royal Society, seeking to guarantee the rights to his inventions. Talbot developed a different process called calotyping, using sheets of paper covered with silver chloride, which were then placed in contact with another paper, producing the positive image. This process is very similar to the photographic process in use today in that it also produces a negative that can be reused to produce multiple positive images. At the time, Hippolyte Bayard also developed a photography method. However, because it took so long to announce it, he could no longer be recognized as its inventor.

In Brazil, the Frenchman living in Campinas (São Paulo), Hércules Florence, achieved better results than Daguerre, as he developed negative results. However, despite attempts to disseminate his invention, which he called "Photographie"-he was the legitimate inventor of the word-he did not get recognition at the time. His life and work were only properly rescued in 1976 by Boris Kossoy.

Photography then became popular as a consumer product from 1888. The Kodak company opened its doors with a marketing speech where everyone could take their pictures, without the need for professional photographers with the introduction of the "coffin" type camera and the film on replaceable rollers created by George Eastman.

Since then, the photographic market has experienced increasing technological evolution, such as the establishment of color film as the standard and automatic focus, or automatic exposure. These innovations undoubtedly make image capture easier, improve reproduction quality or processing speed, but very little has changed in the basic principles of photography.

The major recent change, produced since the end of the 20th century, was the digitalization of photographic systems. Digital photography has changed paradigms in the world of photography, minimizing costs, reducing steps, accelerating processes and facilitating the production, manipulation, storage and transmission of images around the world. The improvement of the digital image reproduction technology has broken barriers of restriction in relation to this system by sectors that still give prestige to the traditional film, and thus, irreversibly expanding the field of digital photography.
