Ever wondered when was photography invented? Joseph Nicéphore Niépce, a Frenchman, is the person who takes the credit for taking the world’s first permanent photograph in around 1826.
Interestingly, though, he did not invent the camera itself. It was another Frenchman who invented the camera, Louis Daguerre.
Following years of trial and experimentation, Niépce was finally successful in making permanent images from nature. He called his process “héliographie”, which translates as “drawing with the sun”.
The earliest surviving image (which you can see above) shows a courtyard at Niépce’s home in Saint-Loup-de-Varennes, France. It was recorded onto a sheet of pewter plate, which was coated with bitumen of Judea – a naturally occurring light-sensitive asphalt.
It took an eight-hour exposure in bright sunshine to produce a positive image, which was complete once the unexposed areas were dissolved in oil of lavender and white petroleum.
Niépce’s 1826 heliograph was dark and blurred, and the plate had to be viewed from a certain angle in order for the details of the building to be visible. Nevertheless, it was a monumental breakthrough.
Niépce had previously made a copy of a 17th-century engraving using the same process. He also made another ‘heliograph’ in 1824 and described it in a letter to his brother: “I have succeeded in obtaining a picture as good as I could wish,” he wrote.
“The objects appear with astonishing sharpness and exactitude down to the smallest details and finest gradations. As the image is almost colorless, one can judge it only by holding it at an angle, and I can tell you the effect is downright magical.” This heliograph has not survived.
Niépce’s pioneering work was not recognized in his lifetime and he died in obscurity in 1833. It wasn’t until 1952 that the photo-historian, Helmut Gernsheim, discovered the image, stored in a London warehouse, and confirmed it as the world’s first photograph.
However, before his death, Niépce shared his process with his business partner – Daguerre, who went on to develop his own groundbreaking “Daguerreotype” process – and would be credited as the inventor of the camera.
The precursor to the camera
Niépce’s new process used a camera obscura to create the image. This optical device could take the form of a light-tight box or a darkened room, with a small hole in one side that lets in light from outside. As light travels in straight lines, the resulting image of the exterior scene is projected, upside-down, onto the surface directly opposite.
The camera obscura had been in use for a long time. The term, first used in 1604 by the German mathematician and astronomer Johannes Kepler, comes from the Latin for “chamber” (“camera”) and “dark” (“obscura”).
The first known use of a camera obscura was in around 400BC, by the Chinese philosopher Mozi. It was later by the Greek philosopher Aristotle. In the 13th century, Roger Bacon described using one to observe a solar eclipse.
Rudimentary lenses were added to the aperture from the 16th century onwards, to give a sharper and more detailed image. By the early 18th century, wooden camera obscura devices were being made that had a distinctly camera-like design.
Images made by a camera obscura were regarded as a visual wonder, a scientifically interesting phenomenon, and a useful drawing aid. However, beyond tracing their outlines by hand, it was impossible to make these images in any way permanent until Niépce’s invention.
Thomas Wedgwood
Thomas Wedgwood (1771-1805) made the earliest documented experiments in recording images on paper and leather coated with light-sensitive silver nitrate – and therefore also has a claim to being the first photographer.
In a letter from the 1790s, inventor and mechanical engineer James Watt wrote that Wedgwood’s primary objective in these “silver pictures” had been “to capture real-world scenes with a camera obscura,” but those attempts failed.
The son of the famous potter Josiah Wedgwood, Thomas Wedgwood did succeed in capturing what Watt described as “silhouette images of objects in contact with the treated surface”, later called photograms. However, as Wedgwood lacked a means to make them permanent, the unexposed areas gradually darkened in daylight.
