The Fascinating History of Photography.
Looking at the history of photography you will realize it was derived from the words “graphein” and “photos” which are Greek. Photos means to light and graphein means to draw. Photography, as a word dates back in the early 1830s. This is not to indicate that people did not know about photography before that time. Evidence shows that this was a practice even 2 millenials before then. In ancient Greek and Chinese history, there are reports of what could be termed as photography. These early photographs are very different from what you can achieve using your smartphone now. Even so, the history is fascinating and rich. If you want to learn the transition from camera obscura to smartphone then keep on reading. The idea in which a dark chamber with a tiny hole on the wall for picture creation was born 2 millenials ago.
Courtesy of the hole, objects on the outside could be projected on the walls of the room. The process is the definition of camera obscura. Fast forward to late 16th century and there were lenses that were helping in the projection and they were in the possession of scientists and the inventors. The picture images were created by tracing the subjects and then filling them in. Nicephore Niepce is one of the inventors with an interest in lithography. If you are wondering what lithography is, it is basically the process of drawing the projected images on the lithographic stone. The end product would then be printed in ink. Niepce then came up with heliography in 1822. It is simply a process in which this process used light from the sun in completing the drawings. Through this process, the oil engravings he had were transferred to various surfaces like stone, zinc, glass and pewter glass. Niepce realized that the method wasn’t enough to come up with paper prints of these documents. In the year 1829, Louis-Jacques- Mande Daguerre partnered with Niepce. He was working towards shortening the amount of needed in the exposure process. Niepce’s partner continued the work after his death and he was able to achieve the goal. He exposed the images to mercury vapor but they had to be on plates of iodized silver. The production time was markedly reduced when Louis-Jacques- Mande Daguerre finally figured out the process. The problem is that the images could not last for long. When such images were exposed to light they would dissolve. In 183, Louis-Jacques- Mande Daguerre was able to make permanent images.
