Stop bath is an acidic solution used for processing black-and-white photographic films, plates, and paper. It is used to neutralize the alkaline developer, thus halting development. [1] Stop bath is commonly a 2% dilution of acetic acid in water, though a 2.5% solution of potassium or sodium metabisulfite works just as well. [1]
Fixation is commonly achieved by treating the film or paper with a solution of thiosulfate salt. Popular salts are sodium thiosulfate—commonly called hypo—and ammonium thiosulfate—commonly used in modern rapid fixer formulae. [1] Fixation by thiosulfate involves these chemical reactions (X = halide, typically Br −): [2]
Sonic Foundry was founded in 1991 and is headquartered in Madison, Wisconsin. The company sold Vegas Pro and Sound Forge, along with other programs (including Acid) to Sony Pictures Digital for US$18 million in 2003, [1] which led to the creation of Sony Creative Software.
Therefore, silver halide crystal size is proportional to film speed. The metallic silver image has dark (black) appearance. Once the desired level of reduction is achieved the development process is halted by washing in a dilute acid and then the undeveloped silver halide is removed by dissolving it in a thiosulfate solution, a process called ...
Sony Creative Software is an American software company that develops various media software suites. Sony Creative Software was created in a 2003 [1] deal with Madison-based media company Sonic Foundry in which it acquired its desktop product line, hired roughly 60% of employees, paid $18 million in cash, and took on certain liabilities and obligations.

There are two versions of the E-6 process. Commercial laboratories use a six-bath chemical process. The 'hobby' type chemistry kits, such as those produced by Tetenal, use three chemical baths that combine the color developer and fogging (reversal) bath solutions, and the pre-bleach, bleach and fixer bath solutions. Rinses, washes, stop baths ...
Sony also manufactured a mini CD burning device, designed to be "PC-free." The device allowed the user to directly burn images from a Memory Stick or a USB flash drive or camera to a mini CD. It was a precursor to the various portable media storage devices such as the iPod Photo adapters and various other hard disk based photo storage units.
