ride containing microcrystals. The silver chloride has considerably smaller absorption and photosensitivity in a short wave part of a spectrum (400450 nm) than silver bromide or bromoiodide. Therefore for reception green and red of photosensitive layers in color photomaterials preferably to use chloride containing photographic emulsions.

In silver processing: Chemical compounds …photosensitive chemicals silver chloride and silver bromide. These silver salts are prepared by adding sodium chloride or sodium bromide to a very pure solution of silver nitrate. The highly insoluble silver chloride or silver bromide then precipitates from solution.
Invents gelatin dry plate silver bromide process, allows for development of exposed negatives at a later time. This innovation frees photographers from having to develop wet plates onsite. 1874 Lewis Hine (USA) Born. Photographer for social reform, he documented Ellis Island immigrants, the slums of NYC and was an advocate for child labor laws.
Bromine itself, as well as some of its compounds, are used in water treatment, and is the precursor of a variety of inorganic compounds with an enormous number of applications ( silver bromide …
A different color coupler is used for each layer of the emulsion and, although the complete color picture is formed in this step, the film is coal black because of the metallic silver produced at the same time. The silver then is oxidized to silver bromide with dichromate solution containing bromide ion and removed with thiosulfate solution.

Silver bromide (AgBr), a chemical used in photography, now accounts for the largest use of bromine. Other bromine compounds are used in fumigants, in flameproofing agents and in …
A silver halide (or silver salt) is one of the chemical compounds that can form between the element silver and one of the halogens . In particular, bromine , chlorine , iodine and fluorine may each combine with silver to produce silver bromide (AgBr), silver chloride (AgCl), silver iodide (AgI), and three forms of silver fluoride , respectively.

Bromine acts as an accelerator to the light sensitivity of the previously iodized plate. Bromine is also used to reduce mercury pollution from coalfired power plants. This can be achieved either by treating activated carbon with bromine or by injecting bromine compounds onto the coal prior to combustion.
Silver bromide (AgBr), an important component of photographic film, is, like silver chloride and iodide, light sensitive. Traces of potassium bromate (KBrO 3) are added to wheat flour to improve baking. Other bromine compounds of significance include hydrogen bromide (HBr), a colourless gas used as a reducing agent and a catalyst in
