Reticulation
cracking or distorting of the emulsion during processing
Sabattier effect
A partial reversal of tones that occurs when film or paper is re-exposed to light during development. Commonly called solarization.
Silver Halides
The light sensitive part of common photographic emulsions; the compounds silver chloride, silver bromide and silver iodide.
