Stages of camera development

 It is interesting to analyze the camera's journey from its original invention to the present day. Many people were involved in the creation of the modern camera, some of whom spent decades inventing it. Inventors sought to invent better cameras than those previously developed, and in the year 1021, the Iraqi scientist Ibn al-Haytham described in his book “The Book of Optics” a device very similar to a camera, beginning the thousand-mile journey in developing the modern camera. In fact, the quality of cameras continues to improve every day.

First camera

The basic concept of photography has been around since approximately the 5th century BC, but the art did not appear until the 11th century when Iraqi scholars developed what is known as the “secret camera.” Even then, this camera did not record images, but simply displayed them on another surface. The first darkroom cameras were made by drilling holes in tents and projecting images from outside the tent into the darkness. The camera obscura did not become small enough to carry until the 17th century. It was around this time that primary lenses appeared for focusing light.

What were the first cameras like?

The first cameras were huge. In fact, the first cameras were so large that they were operated by multiple people. It was the size of a room. It can accommodate several people. Large cameras were used until the 1940s. Some cameras could capture images but could not store them. The photographer had to manually process the images after taking them. At first, the images captured by the cameras were blurry, but things gradually improved. The first cameras could also take black and white images. Color photography did not spread widely and commercially until the 1940s.

Camera history

The camera is an ancient tool, with its first ideas dating back to ancient times, but its design has only recently evolved. In the time of Aristotle, photography was known in the darkroom, and in the period after Leonardo da Vinci there were photography laboratories that painted images on external objects using sunlight. Based on this principle, in 1550 AD, Girolamo Cardano invented an optical lens to facilitate vision, which was a convex lens. In 1658 AD, the scientist Thomas Rasmussen developed the science of photography, followed by the German scientist Johann Zhang in 1685 AD and many others. /In 1839, Daguerre designed the first camera.

The theory he developed, which he called the daguerreotype, was an unprecedented invention that changed a lot at the time. Daguerre relied on many scientists and relied on their works until he presented the world with the photographic machine. One of the most prominent people whom Daguerre relied on was the British scientist Henry Fox Talbot, who was able to place images in a chemical solution before extracting them.

Stages of camera development

Early attempts by photographic pioneers to devise artistic methods to give subjects and models in photographs natural, photographic-like colors were based on several previous inventions, such as Ibn al-Haytham's invention of the darkroom and pinhole techniques, and the action of chemicals in lighting. It is believed to be the result of a combination of inventions. By 1840, inventor Tolt combined the chemical film process with the calotype process, where silver chloride was applied to a layer of paper to create a negative and reproduce a positive image. Film cameras opened the door to photographic technology because they allowed extremely precise photographs to be taken at the touch of a button. A film camera was a machine equipped with a lens that captured the entire scene as light struck it. The image was then printed on a special film on which it was stored and then extracted from the film during the developing process.

By 1950, with the advent of television broadcasting, digital photography technology appeared that converts an optical image into a packet of digital electrical signals. Then, in the 1960s, new types of digital cameras appeared, as Kodak produced the first digital cameras in the 1970s and previous cameras in the 1990s. Although film cameras existed at the same time, digital cameras developed further.

With the advent of the new millennium and the emergence of modern mobile phones, the manufacturers of these phones began to install cameras in them, but the resolution was still very low. But with the advent of smartphones, manufacturers started offering cameras with resolution similar to high-end digital cameras, and users started abandoning these cameras to some extent. In addition, the widespread use of various social media and smartphone applications has made it easier to use many filters and photo editing features so that users can take photos without the need for a professional camera.
