Chemical Reactions Involved in The Process
Reactions involved in the collodion processes are the same as those that apply other photographic processes. The iodide, chloride or bromide salts in the collodion react with silver nitrate to produce silver iodide, silver chloride or silver bromide. These are unstable to light, and are chemically changed upon exposure. They are reduced to metallic silver by the developer.

“We do not want actions, but men; not a chemical drop of water, but rain; the spirit that sheds and showers actions, countless, endless actions.”

“The indications are that swearing preceded the development of cursing. That is, expletives, maledictions, exclamations, and imprecations of the immediately explosive or vituperative kind preceded the speechmaking and later rituals involved in the deliberate apportioning of the fate of an enemy. Swearing of the former variety is from the lips only, but the latter is from the heart. Damn it! is not that same as Damn you!”
—Ashley Montagu (b. 1905)
“Yet I doubt not through the ages one increasing purpose runs,
And the thoughts of men are widened with the process of the suns.”
—Alfred Tennyson (1809–1892)
