Introduction
Photography is an art form that has been around for centuries. But what exactly is photography? The definition of photography is “the art or practice of taking and processing photographs” (Oxford Dictionary). This practice has evolved over time, with the invention of cameras, film, and digital technology. Let’s take a look at the history of photography and when it was invented.
How and When Was Photography Invented?
The invention of photography is credited to two English scientists, William Fox Talbot and John Herschel. In 1839, they both independently developed processes of capturing images on light-sensitive material. Talbot created the calotype photographic process, which involved using paper coated in silver iodide. Herschel developed the cyanotype process, which used iron salts and paper. Both of these processes marked the beginning of modern photography.
Before these inventions, there were various experiments in photography. As early as 1685, German scientist Johann Schulze discovered that mixing chalk and silver nitrate produced a darkening reaction. In 1727, Johann Heinrich Schulze also discovered that this mixture could be used to capture an image. However, none of these experiments led to the development of photography.
To create a photograph, there are several steps. First, light passes through a lens and forms an image on light-sensitive material. Then, the material needs to be exposed to light for a certain amount of time. Lastly, the image needs to be processed to make it visible and permanent.
Exploring the Evolution of Photography
After the invention of photography, the next step was the development of the camera. In the early 19th century, French inventor Joseph Nicéphore Niépce created the first camera, which he called the “camera obscura”. This device was able to capture an image on a metal plate. From there, the technology continued to evolve and improve.
In the late 19th century, color photography emerged. French photographer Louis Ducos du Hauron developed a three-color process that combined red, blue, and yellow exposures to create a full-color image. This process was further improved upon by French physicist Gabriel Lippmann, who developed a method of producing color images without the use of dyes or pigments. This technique, known as “Lippmann photography”, won him the Nobel Prize in Physics in 1908.
The next major development in photography came with the emergence of digital technology. In 1975, Kodak released the first digital camera, which allowed users to store their photos on a memory card. Since then, digital cameras have become increasingly popular and ubiquitous, replacing traditional film cameras.
The Impact of Photography on Society
Since its invention, photography has had a huge impact on society. It has allowed us to document historical events like wars and political protests, as well as everyday life. Photography has also influenced art and culture, inspiring new forms of visual expression.
Photography has also changed the way we view the world. As Pulitzer Prize-winning photojournalist David Hume Kennerly says, “Photography is not just a way of seeing, it’s a way of feeling.” Through photography, we can experience different cultures, explore faraway places, and see the world in a whole new light.
Conclusion
The history of photography is a fascinating one. From its invention by William Fox Talbot and John Herschel to the emergence of digital photography, photography has come a long way. It has changed the way we view the world and has had a profound impact on society. We can only imagine what the future of photography holds.
