ambrotype 的詞源

“ambrotype”是一種在玻璃上拍攝的照片，由銀提供光線，黑色背景提供陰影，可追溯至1855年的美國英語，顯然源自希臘語 ambrotos “不朽的，不滅的”（參見 ambrosia），第二個元素來自 daguerreotype。

This invention consists in an improved process of taking photographic pictures upon glass, and also of beautifying and preserving the same, which process I have styled "ambrotype." My improved process has reference to the art of taking pictures photographically on a film of collodion upon the surface of a sheet of glass, the collodion being suitably prepared for the purpose. By the use of the said process, the beauty and permanency of such pictures are greatly increased, and I have on this account styled the process "ambrotype," from the Greek word ambrotos, immortal.

這項發明涉及在玻璃表面上用膠質膜拍攝照片的藝術，並美化和保護它們的改進過程，我稱之爲“ambrotype”。我的改進過程是指在爲此目的適當準備的玻璃片表面上用膠質膜拍攝照片的藝術。通過使用該過程，這些照片的美麗和持久性得到了極大的提高，因此我將該過程稱爲“ambrotype”，來自希臘語單詞 ambrotos，意爲不朽的。[“James A. Cutting 的專利規範，美國波士頓攝影師，用於在玻璃上拍攝照片的改進過程以及美化和保護同樣的專利，日期爲1854年7月26日，倫敦印刷，1855年9月發表於富蘭克林研究所雜誌]
