Definition
By definition, photography is the technique of creating images by means of light exposure, fixing it on a surface sensitive to light.
The mixture of two knowledges generated the photograph. In other words, even in antiquity, the principle occurred through the observation of physical phenomena. Likewise, much later, in the 19th century, he joined chemistry and, today, digital photography.
In this way, the current title has been reached, it has already had at least two previous names, namely, heliography and daguerreotypy.
Finally, the term photography, used for the first time in Brazil, was coined by a Frenchman in the interior of São Paulo, in 1834.
From the Darkroom to Popularity
Considering the studies of the darkroom, it was only in the first half of the last century that the photo stopped being a form of restricted expression. Until then, only professional photographers and a minimal group of wealthy people had access.
This occurred with the evolution of the process. The improvement of the photosensitive materials and the simplification of the equipment, in this way, made it possible for the consumption and learning of the practice to reach the common citizen.
Improvements have been added to each period. They replaced the exclusive glass plates with flexible black and white films that later became colored and increasingly sensitive.
With that, came the small and powerful reflex cameras and, later, the digital system, which reinvented photographic art.
From the time of the click to the printing of the images, the whole process became more friendly, making the digital photo a “craze”.
With the arrival of the digital system and, soon after, of social networks, we noticed a great increase in the number of new images.
In this way, the coexistence between digital photography and new media has transformed photography into a fundamental element of social communication.
Like its history, the practice of photography is composed of two crucial and connected halves, one of a technical order and the other of an aesthetic order.
