...This is called the talbotype or calotype. In 1851, British photographer Frederick Scott Archer (1813-57) announced the collodion wet plate method, in which silver iodide was dispersed in collodion (nitrocellulose dissolved in ether), applied to a glass plate, and a photograph was taken while it was still wet (wet plate photography). After that, research into photosensitive materials progressed rapidly, and in 1871 the silver bromide gelatin emulsion, the prototype of the emulsion used in modern photographic film, was invented by British photographer R.L. Maddox, which significantly increased the sensitivity of photographic materials and made them easier to handle. *Some of the terminology explanations that mention "Archer, SA" are listed below.

…これをタルボタイプtalbotypeまたはカロタイプcalotypeと呼ぶ。51年にはイギリスのアーチャーFrederick Scott Archer(1813‐57)がヨウ化銀をコロジオン(ニトロセルロースをエーテルに溶解したもの)に分散してガラス板に塗布し,乾かない間に写真を撮影するというコロジオン湿板法を発表した(湿板写真)。 その後,感光材料の研究は急速に進んで1871年には現在の写真フィルムの乳剤の原型である臭化銀ゼラチン乳剤がイギリスのR.L.マドックスによって考案され,写真感光材料の感度が著しく高くなり取扱いも容易になった。… ※「アーチャー,S.A.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
