银版摄影法 Daguerreotype

(重定向自Daguerrotypes)
银版摄影法拍摄的妇女肖像

银版摄影法英语:Daguerreotype)是法国巴黎一家著名歌剧院的首席布景画家达盖尔,于1839年发明的利用水银蒸汽对曝光的银盐涂面进行显影作用的方法。这种摄影方法的曝光时间约为30分钟,大大的短于尼埃普斯的摄影方法。经过改良后,曝光时间进一步缩短,可以拍摄肖像照片。

用这种方法拍摄出的照片具有影纹细腻、色调均匀、不易褪色、复制困难、影像左右相反等特点。这种摄影方法是用达盖尔自己的名字命名的,所以又称为达盖尔银版法

银版摄影法的优点是照片逼真,富立体感,而且是正像。缺点是从不同的角度观看,照片会由正像变成负像。此外,由于影像是在一层很薄的银上形成,因此容易受损,用手指轻擦也可能会令照片受损,现时存世的早期银版照片,有不少都出现破损。后来法国物理学家斐索想出为照片镀金,并在1844年公开「镀金法」这种保护措施,方法是把氯化金加进硫代硫酸钠的水溶液,再洒在照片上形成黄金保护层。一众摄影师则想出更直接的方法,把照片镶在玻璃镜框中。还有,由于使用水银蒸汽显影,有可能导致摄影师水银中毒。其他缺点包括复制照片困难,及拍摄成本高昂。

Daguerreotype 银版摄影法

(重定向自Daguerrotypes)
Daguerreotype of Louis Daguerre in 1844 by Jean-Baptiste Sabatier-Blot
1840–1841 Camerae obscurae and plates for Daguerreotype called
Still life with plaster casts, made by Daguerre in 1837, the earliest reliably dated daguerreotype[26]
The earliest reliably dated photograph of people, taken by Daguerre one spring morning in 1838 from the window of the Diorama, where he lived and worked. It bears the caption huit heure du matin (8 a.m.). Though it shows the busy Boulevard du Temple, the long exposure time (about ten or twelve minutes) meant that moving traffic cannot be seen; however, the bootblack and his customer at lower left remained still long enough to be distinctly visible. The building signage at the upper left shows that the image is laterally (left-right) reversed, as were most daguerreotypes. Daguerre presented this daguerreotype together with two others: a still-life and a view from the same window labelled midi (noon) to King Ludwig I of Bavaria (The Munich Triptych) in order to publicise his invention. All three daguerreotypes were destroyed by cleaning in 1974 but they are preserved in reproduction.[27]

Daguerreotype (/dəˈɡɛrəˌtp, -r-, -riə-, -ri-/; French:daguerréotype) process, or daguerreotypy, was the first publicly announced photographic process, and for nearly twenty years, it was the one most commonly used. It was invented by Louis-Jaques-Mandé Daguerre and introduced worldwide in 1839. By 1860, new processes which were less expensive and produced more easily viewed images had almost completely replaced it. During the past few decades, there has been a small-scale revival of daguerreotypy among photographers interested in making artistic use of early photographic processes.
