On the performance of colours - Plant-based spectral photographs by John F. W. Herschel (1792-1871) and the network of experimental practices of scien

卡罗琳的项目是第一个重复约翰F. W。赫歇尔研究了光对植物和矿物的摄影作用，创造了太阳光谱的多色印象，并与科学家玛丽萨默维尔和化学家/作家罗伯特亨特进行了生动的通信。只有一小部分实验被提交给了皇家学会（1840/1842），尽管未发表的笔记本条目将研究范围从1829年扩大到1858年。这些实验是对光谱学的早期贡献，早于彩色摄影，并发现了摄影彩色生产的基本概念。在摄影史上，这些早期的调查几乎被忽视，它们构成了彩色摄影研究的一个重要但未被充分研究的方面。

Carolin's project is the first to reperform experiments by John F.W. Herschel that studied the photographic action of light on plants and minerals, creating multi-coloured impressions of the solar spectrum and instigating a lively correspondence with scientist Mary Sommerville and chemist/writer Robert Hunt. Only a small set of experiments was communicated to the Royal Society (1840/1842), though unpublished notebook entries expand the investigation from 1829 to 1858. The experiments are an early contribution to spectroscopy, predate colour photography and discovered fundamental concepts of photographic colour production. Largely overlooked in photographic histories, these early investigations form an important but understudied aspect of colour photography studies.
