Short version: the developer converts silver halide that was energized by light into black metallic silver. Unexposed halides are washed away by the fixer, leaving varying densities of black metallic silver in the black and white film. In the color process, intermediate steps replace the bms with dyes.

What does STTP do in a photographic film developing formula?
In the processing of photographic films, plates or papers, the photographic developer (or just developer) is a chemical that makes the latent image Latent_imageonthe film or print visible. It does this by reducing the silver halides that have been exposed to light to elemental silver in the gelatin matrix. As a generalisation, the longer a developer is allowed to work, the greater the degree of reduction of the silver halide crystals to silver and therefore the darker the image.
Is silver chloride used in photography?
Yes, silver chloride is used in photography as a light-sensitive chemical in the production of black-and-white photographic papers. When exposed to light, silver chloride undergoes a chemical reaction that forms an image on the photographic paper.
What is silver bromide used for?
Silver bromide is commonly used in photography as a light-sensitive material in film and photographic papers. When exposed to light, silver bromide undergoes a chemical reaction that results in the formation of a latent image, which can be developed to produce a visible image.
Why should you store silver bromide in brown bottles?
Silver bromide reacts chemically when exposed to light, which is why they use it to make photographic papers.
What light sensitive chemical is used in photographic paper?
All photographic papers consist of a light-sensitive emulsion, consisting of silver halide salts suspended in a colloidal material - usually gelatin- coated onto a paper, resin coated paper or polyester support. from wikipedia.com

What is the name of the compound Ag Br?
The compound AgBr is called silver bromide, which is a white solid commonly used in photographic films and papers due to its light sensitivity.
What is silver bromide?
Silver bromide is a chemical compound composed of silver and bromine atoms. It is commonly used in photographic films and papers due to its light sensitivity, allowing it to be exposed to light to create a photographic image. Silver bromide is insoluble in water and has a pale yellow color.
What has the author George Frank Duffin written?
George Frank Duffin was a mathematician known for his work in various areas, including complex analysis and integral equations. He wrote several influential papers and books on these topics, contributing to the field of mathematics.
Where can microscope images be found?
Microscope images can be found in scientific research papers, textbooks, online databases, and educational websites. Organizations like the National Institutes of Health (NIH) and universities often have digital libraries dedicated to sharing microscope images with the public. Additionally, you can find microscope images on platforms like Google Images and Flickr.
What is dektol?
Dektol is the patented trade name of a single-powder cold-tone black and white paper developer from Eastman Kodak. It is one of the oldest and most flexible black and white paper developers made, and so far as I know is still manufactured by Kodak in an envelope of dry powder to make one gallon of concentrated liquid developer, which is then diluted to a working solution by mixing one part of concentrate with two parts of water (1:2). Dektol is primarily for use with cold or neutral tone papers. It will work well with multigrade papers. It is not formulated for warm tone papers although it will develop them, but not to their warmest tones.
Was the Vietnam war censored?
No, journalists could show whatever they wanted, which contributed towards the outrage during the peace movements. Horrific images would sell the most papers.
