ambrotype 的词源

这是一种在玻璃上拍摄的照片，利用银光和深色背景透出的阴影效果，1855年，使用美式英语。这个词显然源自希腊语 ambrotos，意为“不朽的，永恒的”（参见 ambrosia），其中的第二部分来自 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.

这种发明是一个改进的过程，用于在玻璃上拍摄摄影图片，同时也能美化和保存这些图片。我将这个过程称为“ambrotype”。我的改进过程涉及在涂层薄膜上，通过适当准备的涂层在玻璃表面拍摄照片。通过这种方法，这些照片的美观性和持久性都得到了极大提升，因此我将这个过程称为“ambrotype”，源自希腊语中的“ambrotos”，意为不朽。[“专利说明书，授予美国波士顿的摄影师詹姆斯·A·卡廷，关于在玻璃上拍摄摄影图片的改进过程，以及美化和保存这些图片的技术。日期：1854年7月26日，伦敦，发表于《富兰克林学会杂志》，1855年9月。”]
