At the same time, English scientist W. Talbot invented a method called talbotype, in which the photosensitive material was paper soaked in a silver nitrate solution and, after drying, dipped in a solution of sodium chloride or bromide. The negative exposed in the camera was developed with a gallic acid solution, fixed with sodium thiosulfate, rinsed, and dried. Daguerreotype, however, gained much greater popularity.
- In 1840, Hungarian mathematician J.M. Petzwal built a portrait lens, reducing portrait time to one minute.
- A year later, the first metal camera by Voigtlaender appeared.
- In 1851, English photographer Frederick Archer and French photographer Gustave Le Gray introduced the collodion process (using glass plates coated with collodion - a mixture of alcohol and ether, developed in acid. They had to be exposed while wet).
- 1855 - English physicist James Maxwell produced the first color photographic images, using the principle of additive color mixing.
- In 1862, Englishman Charles Russell discovered a method of chemical development in an alkaline environment.
- In 1873, German chemist Hermann Vogel developed optical sensitization (increasing light sensitivity and expanding the range of photosensitive materials).
- 1874 - Frenchman Ducos du Hauron invented the first practical autochrome method, where light passed through a layer of colored grains (the raster) before reaching the photosensitive emulsion. During development, color appeared from the colored raster grains.
- From 1887 to 1889, Americans Hannibal Goodwin and George Eastman (independently) invented celluloid photographic film.
- In 1890, the first anastigmat was created (a lens system that provided a clear, undistorted image of all points in the subject).
- 1910-1914 - German chemist Rudolf Fischer developed the principle of multilayer photosensitive material and color development (simultaneous image formation in each layer - black and white and color. The images in each layer combined to form a color image). These principles came into use about 20 years later by KODAK (USA) and AGFA (Germany).
- In 1925, infrared-sensitive plates were introduced.
- 1926 brought a revolution with the appearance of the first 35mm Leica camera, sparking rapid development in photojournalism, which reached its peak after World War II.
- 1929 - the first twin-lens reflex camera, Rolleiflex.
- 1936 - the 35mm single-lens reflex camera, Exakta.
In the 1930s, magnesium flash lamps appeared worldwide - magnesium powder was poured onto a glass plate and ignited just before taking a picture. This method was dangerous, leading many photojournalists to suffer severe burns, loss of eyes, fingers, and sometimes entire hands.
Only after press magnate William Hearst fell victim to such a flash did he order all his photojournalists to use the new magnesium bulbs, which dominated the market from the 1940s. They were slightly less dangerous but often exploded. True progress came with electronic flash units housed in substantial cases and powered by batteries. Photojournalists resembled burdened camels, but they were safe.
- 1941-42 - diffusion copying method (photographic reproduction).
- 1947 - the "one-minute" Polaroid-Land camera and pentaprism (light rays reflected from the reflex mirror are bounced three times, making the viewfinder image upright and not inverted).
- 1954 - the 6x6 cm single-lens reflex camera, Hasselblad.
- 1964 - Voigtlaender’s Zoomar variable focal length lens.
- 1966 - the introduction of electronic components in cameras began.

History of media and journalism. The biggest titles, famous journalists, groundbreaking events in the press, radio, television and internet industries in the world. Stories developed and told by Małgorzata and Bartłomiej Dwornik from the online weekly Reporterzy.info.
Népszava. The history of Hungary's oldest newspaper
Małgorzata Dwornik
The first editor used a pseudonym. The paper was printed in both Hungarian and German. The military destroyed the newsroom. Journalists died in the Danube’s currents. Népszava survived monarchy, dictatorships, and revolution. And it still exists.
Kuensel. History of a newspaper from Bhutan that even the illiterate read
Małgorzata Dwornik
Rockman as editor in chief, a newspaper without ads, news in comics, and distribution by bus drivers. The history of Kuensel, Bhutan's first newspaper, dates back to 1965 but it was only a decade later that things really got serious. With help from the Japanese and a young journalist trained in Australia.

Atuagagdliutit Grønlandsposten. The history of Greenlandic News
Małgorzata Dwornik
The first issue, published in 1861, had eight pages, an unusual column numbering system, and a print run of 300 copies. At the time, it was one of the few illustrated newspapers in the world and the first to print in color. Its purpose was to encourage Greenlanders to read - a mission it has continued for 163 years. Today, its motto is: "A week without AG is not a real week".
Vanuatu Daily Post. 30 years of struggle (including fistfights) for free media
Małgorzata Dwornik
Ambition and hard work are not enough to keep a newspaper running. The most popular title in exotic Vanuatu today nearly shared the fate of its many forgotten predecessors. But fate had other plans - thanks to an unexpected reunion and... a phone book. What followed was even more interesting. And not always safe.
The Fourth Estate in America
Urszula Sienkiewicz
Success, prestige, power, but above all, big money - these are the first words associated with the world of media in the United States. Do American media truly wield such influence over business and politics in the USA that they can be called the "fourth estate" without hesitation?
The Kathmandu Post. History of Nepal's first independent daily newspaper
Małgorzata Dwornik
The first issue of The Kathmandu Post was published on Thursday, February 17, 1993. It had eight pages and aimed to fight injustice. Within a week, it became the most-read publication in the country, though not everyone welcomed its success.
