Techniques Glossary Fixer
Chemical used after developing and before washing to remove remaining light-sensitive halides by converting them into soluble salts. An image becomes stable to light once it's fixed.
Fixer is used for processing all commonly used films, including black-and-white films, Kodachrome, and chromogenic films. In chromogenic films, the remaining silver must be removed by a chemical called a bleach fix, sometimes shortened to blix.
Fixer (Hypo)-A chemical, sodium thiosulfate, used to remove residual silver halides (grain) from films and prints when processing them. Fixer "fixes" the remaining silver halides in place on either film or prints. Fixer is also called hypo.
Fixer. Solution, usually based on sodium thiosulphate, in which films or prints are immersed after development to convert the unexposed silver halides in the emulsion to soluble products that can be washed out. This prevents subsequent deterioration of the image.
FIXER or "Fixing bath" or "Hypo" - The chemical solution used for fixation. It removes any photo-sensitive silver-halide crystals that were not acted upon by light or by the developer.
FLARE can show up as a plain area of unwanted bright light or in shapes matching the aperture.
Fixer. Chemical (basically a solution of sodium thiosulfate plus potassium metabisulfite as acidifier). Used after development to make soluble those parts of a photographic image unaffected by the developer. Photographs can thereafter be handled in normal lighting.
A chemical solution (sodium thiosulfate or ammonium thiosulfate) that makes a photographic image sensitive to light. The fixer stabilizes the emulsion by converting the undeveloped silver halides into water-soluble compounds, which can then be dissolved away. Also called hypo.
Step 4: Fixer
Make sure it's at the right temperature and pour it into the developing tank. Agitate the tank a little and let sit for 3 to 3 1/2 minutes, using the agitation stick every minute.
Pour the fixer out and rinse the tank.
Fixer: Fixers dissolve the undeveloped silver salts, which can then be removed by washing. If this step were not carried out, the unactivated silver salts would become activated when exposed to light and cause fogging of the image.
New fixer takes about 3 1/2 minutes, and as you recycle your fixer it will take up to 8 minutes to properly fix your negatives. Once your negatives are similar to the ones shown pour your fixer back into it’s container.
After the fixer, the wet plate is washed in water once more for around 15 minutes before it's dried on the rack. It also can be dried gently over open flame to heat the plate for the next step, which is varnish.
fixer Chemical solution used after development. Converts unexposed and therefore undeveloped silver halide into soluble salts which can be washed out leaving behind the now stable silver image and rendering the film insensitive to light. f-stop or f-number Relative size of a lens aperture.
Prepare the photo fixer.
Prepare another tray that is of a similar size to the one used previously with photo fixer. You can obtain photo fixer at most arts and crafts or photography stores, and should provide information as to the appropriate amount of water to add to the liquid.
the film vigorously in the stop bath and initially in the fixer because gases are released in these solutions and there is danger of air bubbles forming on the film surface. If you allow these air bells, or bubbles, to form, they may cause dark spots.
Acid fixer: A chemical used to neutralize alkali. It is used in the final stage of processing to stop the action of alkaline bath.
Additive color process: A method of producing color images by mixing the three primary colors, red, blue, and green.
Decided to try Kodak T400CN Professional (C41 - B&W) as my wife complains every time I come home stinking of fixer - she REALLY hates it and I have to get straight in the shower. This, at least would reduce the pain.

AGITATION - Gentle movement of liquid photo-processing chemicals (developer, stop-bath, fixer) during processing of film or paper in order to achieve uniform results.
AIR - A relatively large area of white space in a layout.
I loved high-contrast printing using Agfa #6 high-contrast paper. This legendary paper’s characteristics were that it produced practically no midtones.
