Is sodium thiosulphate used in photography?

Photographic fixing agent. An emulsion of sodium thiosulfate (called hypo by photographers) is used to stop development of exposed film. Thiosulfate converts undeveloped silver bromide grains in the film into water-soluble silver thiosulfate complexes that can be removed when the film is washed.S2O32- + AgBr(s) AgS2O3- + Br-S2O32- + AgS2O3- Ag(S2O3)23-Thiosulfate is also an antidote for cyanide poisoning. It reacts with cyanide to produce sulfite and thiocyanate ions:CN- + S2O32- SCN- + SO32-This reaction is catalyzed by an enzyme produced by cell mitochondria to neutralize small quantities of ingested cyanide (which occurs naturally in cassava root, lima beans, and almonds!).

Where was photography created?

The idea of permanently capturing an image on a substrate was thought of by Thomas Wedgwood in England, but his early attempts used silver nitrate without a fixing agent, meaning the images could not leave darkened rooms. The first known photograph taken by a camera is credited to French inventor Joseph Nicéphore Niépce, who in 1826 successfully captured a permanent image using a camera obscura.
