Photo technology pioneers
The pioneers of photo technology determined the history of photography for around a century - from the early years (early 19th century ) to the industrialization of photographic processes (early 20th century ); From around the 1940s it becomes increasingly difficult to trace inventions back to individual people; From this time on, developments are mainly carried out by engineers in teamwork or under the umbrella of the research and development department of a company in the photo industry.
The lists are sorted according to the year of birth.
Early photographic processes through to the first color photography
- Johann Heinrich Schulze - Discovery of the sensitivity of silver salts to light
- Joseph Nicéphore Niépce - inventor of heliography ; first photograph on chlorine silver paper
- Thomas Wedgwood - Contact copies of leaves on glass coated with silver chloride
- Joseph Lemling - Development of the first photographic positive process with iodized silver paper
- Louis Daguerre - inventor of the daguerreotype
- John Frederick William Herschel - Application of the light sensitivity of certain iron salts
- William Henry Fox Talbot - Development of the negative-positive process calotype or talbotype
- Hippolyte Bayard - inventor of the direct positive process
- Claude Félix Abel Niépce de Saint-Victor - creation of photographs on glass using the albumen process ; one of the first color photographs, but without fixation
- Jacob Wothly - Development of the Wothlytypie for the production of positive images using a uranium salt
- Frederick Scott Archer - Development of the collodion wet plate based on the calotype (the ambrotype )
- Richard Leach Maddox - the first dry plate with a sensitivity equivalent to that of the previously used wet plate, with a silver bromide gelatine layer
- Hermann Wilhelm Vogel - investigation of the sensitisers such as collodion for photographs in the correct tonal values ; Developer of a photometer
- Sergei Michailowitsch Prokudin-Gorski - Development of color photographs with the 3 color filters red, green and blue
- Wilhelm Cronenberg - German patent (1898) for the "process for the production of autothpie cliches using collotype plates" and Austrian patent (1903) for "three and multi-color printing on metal and stone" ( photolithography )
