- An accomplished chemist, Herschel discovered the action of hyposulfite of soda on silver salts, which lead to the use of “hypo” as the most effective fixing agent for silver-based photography. Herschel also endorsed and encouraged the term “photography” and coined the terms “negative” and “positive” to refer to photographic images.

He named seven moons of Saturn and four moons of Uranus – the seventh planet, discovered by his father Sir William Herschel. He made many contributions to the science of photography, and investigated colour blindness and the chemical power of ultraviolet rays.
Mar 7, 2023 · Herschel originated the use of the Julian day system in astronomy and named seven moons of Saturn and four moons of Uranus. He made many contributions to the science of photography, and investigated colour blindness and the chemical power of ultraviolet rays.
Although John Herschel did not directly develop the cyanotype process, he made important contributions to the field of photography. His most notable contribution was the invention of the blueprint process, which had significant implications for both photography and scientific documentation.
Feb 16, 2024 · One of his most important papers, ‘On the Art of Photography; or the Application of the Chemical Rays of Light to the Purpose of Pictorial Presentation’, was read to the Royal Society on March 14, 1839. In this paper Herschel put to use the word ‘photography’, ‘emulsion’, ‘positive’ and ‘negative’.”
Feb 21, 2024 · An accomplished chemist, Herschel discovered the action of hyposulfite of soda on otherwise insoluble silver salts in 1819, which led to the use of "hypo" as a fixing agent in photography. In 1839, independently of William Henry Fox Talbot, Herschel also invented a photographic process using sensitized paper.

Because Herschel’s photography has been studied largely through the lens of the history of photography, discussions are often inflected by various origin stories that privilege, for better or worse, the creation of recognizable, fixed images.
