Images have been projected onto surfaces for generations. As early as the 16th century, artists employed the camera obscura and camera lucida to trace scenes. These early cameras just projected what was seen via a hole in a wall of a darkened room onto a surface; they did not freeze an image in time. In essence, the space was transformed into a sizable pinhole camera. In fact, the term “camera obscura” literally translates to “darkened room,” and all modern cameras have been given this designation.
The image created in 1826 by the French inventor Nicéphore Niépce on a polished pewter plate covered in a petroleum byproduct called bitumen of Judea is regarded as the first photograph. It took an eight-hour exposure in direct sunlight to produce with a camera. A silver and chalk mixture darkens when exposed to light, as Johann Heinrich Schultz discovered in 1724. However, this procedure proved to be a dead end, and Niépce started working with silver compounds.
In collaboration, Niépce from Chalon-sur-Saône and the artist Louis Daguerre from Paris improved the already-in-use silver method. Niépce passed away from a stroke in 1833 and left Daguerre his notes. Daguerre made two crucial contributions despite having no scientific training.
He found that a latent picture could be generated and rendered visible by first exposing the silver to iodine vapour before exposure to light and then to mercury fumes after the photograph was taken. The image might then be fixed by submerging the plate in a salt solution.
Daguerre claimed to have created the Daguerreotype, a silver-on-copper plate method, in 1839. Polaroids are being created using a similar procedure today. The patent was purchased by the French government and made available to the public right away.
William Fox Talbot had before developed a different way to correct a silver process image over the English Channel but had kept it a secret. Reading about Daguerre’s discovery inspired Talbot to improve his own method, and by 1840 he had created the calotype technique, which could be quick enough to snap images of individuals like Daguerre had done.
To make an intermediate negative image, he coated paper sheets in silver chloride. Calotype negatives, unlike daguerreotypes, may be used to make positive prints, just like most chemical films do today. This method was patented by Talbot, which significantly restricted its uptake.
He spent the remainder of his life fighting the patent in court until he gave up taking pictures completely. The fundamental technique utilised by chemical film cameras today, however, was later improved upon by George Eastman. Additionally, Hippolyte Bayard created a photographic technique but kept it a secret so that he wouldn’t be credited as its creator.

The collodion process was created by Frederick Scott Archer in 1851. Lewis Carroll followed this method.
The technical process for creating photos on glass was created in 1841 by Slovene Janez Puhar. On July 17th, 1852, in Paris, the Académie Nationale Agricole, Manufacturière et Commerciale honoured the invention.
During the Industrial Revolution, the middle class began to demand portraiture, and the Daguerreotype quickly gained popularity as a solution. It’s possible that this desire, which oil painting was unable to satisfy both cost-effectively and in scale, was what pushed photography’s growth.
Daguerreotypes, while stunning, were delicate and challenging to duplicate. In 2006, a single portrait studio photograph might have cost US$1000. Photographers additionally inspired chemists to improve the technique for producing several copies at a low cost, which ultimately brought them back to Talbot’s method. Over the course of the first 20 years, numerous adjustments and advancements led to the development of the contemporary photographic process.
In order to eliminate the necessity for a photographer to transport boxes of dangerous chemicals and photographic plates, George Eastman of Rochester, New York, invented dry gel on paper, or film, in 1884. Eastman’s Kodak camera debuted on the market in July 1888 with the tagline “You press the button, we do the rest.” Now, anyone could take a picture and let professionals handle the tricky portions of the procedure. With the release of the Kodak Brownie in 1901, photography became widely accessible.
Since then, automatic focus and exposure have also become standards, as has colour film. Since digital cameras allow for quick previews on LCD screens and the resolution of top-of-the-line models has surpassed that of high-quality 35mm film while lower resolution models have become more accessible, digital recording of images is becoming more and more prevalent. Since the advent of the 35mm film Leica camera in 1925, very little has changed for the amateur photographer developing black and white film.
