Photography consists of using, projecting and fixing light in the form of an image within a sensitive medium (physical or digital), to appear in the last form that we see, So what is photography, And how it arose and what is this artistic technique that millions practice, In addition to its existing characteristics and types, “RSMAT” reviews you so in this topic.
What is Photography?
“Photography” is a technique and art form consisting of capturing images using light, displaying them and fixing them on a medium, This medium can be physical or digital, All photography is based on the same principle, which is the “dark camera”, It is an optical instrument consisting of a completely dark chamber with a small opening at one end, Through which light enters and displays on the dark background shadows or drawings of what is happening outside the cabin, but in reverse, Here we recall that the first person to invent this tool was “Ibn al-Haytham”.
In the case of modern cameras, The principle is exactly the same, Except that they are equipped with lenses to increase the focus of what is displayed, and mirrors to re-flip the displayed image, And finally a light-sensitive tape (or similar digital sensor), Who takes the picture and saves it, Later you can print or view them digitally.
The drawings obtained in this way are called photographs, It is the result of decades of mastery of light-sensitive technologies and materials, Until the visual quality of modern cameras was achieved, In addition This technology allowed the development and improvement of other similar technologies, Including cinematography of course.
The beginning of instant cameras and their stages of development
Edwin Land invented the first instant camera for photography and it was produced by Polaroid in 1948.
But before the invention of the instant photographic camera, There were attempts to capture the visual image, Using heliographic drilling and patterns called “dageria”, These techniques came before the beginning of the nineteenth century and were fairly successful at that time, But it was expensive and the images were presented completely blurred.
Photography was then invented in a modern way during the transition to industrial society, This is in obedience to the spirit of the age, which longed for objectivity and all that was sophisticated.
Photography initially inherited its use of photosensitive silverware films of the Dagri type, It was then developed with mercury vapors, But these were toxic elements and successive scientists and inventors in the nineteenth century came up with better methods and better results. Until the appearance of bromide plates in 1871, Then photographic films that were first used in Kodak cameras in 1888.
Next, The technique did not stop developing, in 1907 the brothers “Auguste and Louis Lumière” invented color photography, In 1931 the first electronic flash was achieved, In 1948, polaroid sheets were introduced into imaging processes. In 1990 photography was digitized.
The role of photography in modern society
Photography plays an important documentary and journalistic role today, Because it allows real images to be captured and reproduced in physical or digital media, Hence the ability to observe events that have occurred in other historical places or times.
Today, journalism, science and history cannot be separated from photography. Albums and photo frames were available in any home in the twentieth century and even in the twenty-first century. Now the places where images are collected are different, they are digital and are collected in the hard drives of a computer, smartphone or even social networks.
On the other hand, Geography, astronomy and other applied sciences have found photography an opportunity to capture and zoom in on distant or very small objects. Hence the ability to disseminate them at scale.
Types of photography
According to the nature of the thing depicted we can divide photography into:
- Advertising photography, It serves as advertising or promotion of consumer products, of any kind, The goal of such intervention is often to promote or “correct” misinformation about a product or service.
- fashion photography, It is the kind that is present in celebrations, art shows, fashion events, etc. To focus on the way you dress and the overall appearance.
- Documentary photography, Also called historical or journalist, It is conducted for informational or educational purposes, That is, as part of the transmission of a message.
- landscape photography, In which pictures are taken to show nature at its best, The shots are taken aerial or underwater, On the surface of the Earth, The images are usually very wide and full of color.
- Scientific Photography, Those images that natural scientists take through telescopes, microscopes and other instruments, To show what cannot be observed with the naked eye.
- Artistic Photography, A person who pursues aesthetic purposes, such as, portraits, montages, installations, and so on.
Photography is an art and a profession
Photography was not initially considered an art, Since in its beginnings it lacked diffusion and acceptance, In the past, they preferred painting as an artistic means of representing reality.
However, Throughout the twentieth century, Photography developed and new aesthetic trends were introduced that opened the way for the art of photography to show its own potential, He believed he was doing nothing more than showing the objects placed in front of the camera, But now it represents much more than that.
