论文摘要
埃德蒙·贝克雷尔（Edmond Becquerel）制作的光色图像的过程（这是第一批颜色的照片）仍然很了解。特别是，这些图像的颜色的起源引起了一场持久的辩论，从1848年的Becquerel出版到19世纪末。在实验室中复制了这种摄影过程，并通过可见光谱学研究了敏化板的颜色。对Becquerel写作所改编的灵敏度途径的全面描述。对展示步骤的研究使我们能够对敏化板的色化机理进行见解，并在Becquerel开发的两种敏化路线与光谱敏感性和色彩忠诚方面进行比较。发现所谓的“电化学敏化”样品比“沉浸式敏感性”的样品更敏感，并达到更大的色彩空间。最后，提出了一种可重现的创建彩色样品的方法。
Edmond Becquerel's process of making photochromatic images, which are the first colours photographs, is still poorly understood. In particular, the origin of the colours of these images gave rise to a long-lasting debate, starting from the publication of Becquerel in 1848 until the end of the 19th century. This photographic process was replicated in the laboratory, and the colouration of the sensitized plates was studied by means of visible spectroscopy. A comprehensive description of the sensitization routes that were adapted from Becquerel's writing is given. The study of the exposition step allowed us to gain insights in the colouration mechanisms of the sensitized plates, and to compare between the two sensitization routes developed by Becquerel in terms of spectral sensitivity and colour faithfulness. The so-called "electrochemically sensitized" samples were found to be more sensitive and to reach a larger chromatic space than the "immersion-sensitized" ones. Finally, a reproducible way of creating coloured samples is suggested.
