Scope note
Negatives produced by the wet collodion process.The glass plates remain wet with silver iodide droplets during exposure to light. These negatives are created by pouring collodion onto a clean piece of clear glass to produce an even coating. Before the ether and alcohol evaporates from the collodion, the plate is dipped into a solution of silver nitrate in a darkroom. The silver nitrate bonds with the potassium iodide in the collodion to produce light-sensitive silver iodide. After exposure the plates are developed in a solution of pyrogallic and acetic acids, washed, fixed, dried and varnished.
English
Märgkolloodiumprotsessiga valmistatud negatiivid. Valgusega säritamise ajal on klaasplaadid hõbejodiidi piiskadest niisked. Selliseid negatiive valmistatakse kolloodiumemulsiooni valamisega puhtale läbipaistvale klaasile, et saada tasane kattekiht. Enne kui eeter ja alkohol kolloodiumemulsioonist lendub, kastetakse plaati pimikus hõbenitraadi lahusesse. Hõbenitraat ühineb kolloodiumemulsioonis kaaliumjodiidiga ning tekitab valgustundliku hõbeiodiidi. Pärast säritamist ilmutatakse plaate pürogallushappe ja äädikhappe lahustes, pestakse, kinnistatakse, kuivatatakse ja lakitakse.
