FIXATION - In negatives and prints alike, the conversion of unused silver halides to a soluble silver so that the image remains stable and unalterable when exposed to light. Also known as "fixing." ...
Fixation - chemical bath which converts unused halides to a soluble silver complex in both negatives and prints, making the image stable in white light.
chemical fixation
a hazardous waste treatment process involving reactions between certain chemicals, resulting in solids which encapsulate, immobilize, or otherwise tie up components in the waste, ...
A plain water rinse bath is commonly used between development and fixation to slow down the development by removing all the developer that is clinging to the film (or paper) surface. A rinse bath does not completely stop development but retards it.
Fixing: Chemical used for fixation of an image.
Flare: Scattered light produced by reflections inside the lens. It reduces contrast and shadow detail.
Successful selenium or sulfide toning requires complete fixation. In other cases, the silver may be chemically bleached using a potassium hexacyanoferrate (III) solution and then re-developed in a range of toning formulations.
6 Pour in the fixer , agitate continuously for 30 seconds then intermittently for the duration of fixation. Read the instructions. Usually 4 or 5 minutes.
The fixer is another story about silver halides you probably don't need to hear.
The tools you need will be pretty basic and depend on the fixation method you choose: screwdriver/hammer/brush (for the glue), a saw to cut the timber, meter/square, and a pencil.
Acid rinse
A weak acid solution used after development and before fixation. By neutralizing alkaline developer left on the photographic material it arrests development.

10.) No junk hanging off the strap or your camera: it's just a strap, a small pad, and ingenious fixation devices on each end.
Stop-bath. Stage in processing that arrests the action of the previous solution (e.g. a weak solution of acetic acid used between development and fixation).
Stop down. To decrease the size of the lens aperture. The opposite of open up.
