トリビアの泉:Sepiaってな~に?
Sepia tone refers to the coloring of a black and white photographic print or motion picture film that has been toned with a sepia toner to simulate the faded brownish color of some early photographs. This process can be simulated using a computer and digital photo-editing software.
Sepia语源自用墨鱼的墨汁制造的染料。
Beginning in the 1880s, sepia was produced by adding a pigment made from the Sepia cuttlefish, found in the English channel to the positive print of a photograph. The chemical process involved converts any remaining metallic silver to a sulphide which is much more resistant to breakdown over time. This is why many old photographs are sepia toned—those are the ones that have survived until today.
Although sepia toning began as a printing method, today it is seen as a genre, much like black and white photography.
最初是为了让照片能够保存更长时间,在印像的时候用化学方法将金属银(黑白照片的黑色部分是被还原为的金属银,单质的金属银却是银色,不可思议哦)用化学处理转化为褐色的硫化银,这就是那些褐色的黑白照片能够保存至今的原因。虽然它曾经只是一种印刷方法,现在已经成为类似黑白照片的一个门类。
因为这种能够让照片保存至今的技术而让我们现在能看到很老的照片,可能是对过去的怀旧情趣吧,爱屋及乌地Sepia这种色调被赋予了Vintage的印象。 |
