A wide variety of chemicals are used in black and white photographic processing. Film developing is usually done in closed canisters. Print processing uses tray processing, with successive developing baths, stop baths, fixing baths, and rinse steps. Other treatments include use of hardeners, intensifiers, reducers, toners, and hypo Size: KB. available where photo chemicals are used or mixed due to their corrosive and/or toxic properties. In case of eye or skin contact, rinse for at least minutes Ø A fume hood should be used when mixing powered, toxic, volatile or corrosive chemicals Ø Ensure File Size: 36KB. The photographic chemicals used for developing are different for processing color film and black-and-white film. Both processing methods include developers, stop bathes, and fixers, but black-and-white film is easier to develop because it's all one color. > Chemicals; Narrow Results. Category.

Technology of photography - Technology of photography - Black-and-white processing and printing: Amateurs usually process films in developing tanks. In this type of development roll or miniature film is wound around a reel with a spiral groove, which keeps adjacent turns separated and allows access by the processing solutions. Once the tank is loaded (in the dark), processing takes place in. The photography book.

A glass photographic positive was put over the sensitized plate and used to make the image. Nature made the faithful original photographic drawing, but, in the final prints, carbon-based ink relied on nothing light-sensitive and preserved the original image for posterity. This was the direct forerunner of the photogravure process.
The first commercialized photographic imaging technique, the daguerreotype, consisted of a copper plate, coated in silver and then exposed to iodine vapor. Once the plate had been exposed to light (and we are talking exposures on the order of minutes - far longer than the 1/ of a second our cameras do today) the image was rendered with. Basic Film Developing Chemicals and Their Purposes 6 Share Tweet. Unlike many might think, there are not many chemicals that are used to develop a roll of film. In Black & White film development, you really only need to get familiar with the developer, the fixer, and the stop bath. If you use a septic tank system use caution with photo chemical disposal. Lots of water in the method recommended above is your friend. Using the product Rid-x on occasion to keep your bacteria level as it should be is also recommended. I lived with a septic system for many years and kept it healthy and happy this way. Many photographic chemicals use non-biodegradable compounds, such as EDTA, DTPA, NTA and borate. EDTA, DTPA, and NTA are very often used as chelating agents in all processing solutions, particularly in developers and washing aid solutions. EDTA and other polyamine polycarboxylic acids are used as iron ligands in colour bleach solutions.
