Excerpt from The Chemical Effect of the Spectrum
Berard made another very interesting experiment. He col lected by means of a lens the rays of the spectrum between the violet and the green, to form a beam of white light, and he proceeded in the same way to produce a brilliant white point by collecting the rays between the yellow and the red: despite the heat of this beam, it had no action on silver chloride, although the exposure was prolonged for two hours. The other beam, although less intense, blackened silver chloride in ten minutes.

Paperback. Zustand: New. Print on Demand. This book delves into the chemical reactions of silver compounds when exposed to light. Recognized for its historical significance, this work established that different light rays have varying chemical effects. Since the discovery of photography, the author describes how photographic preparations have traditionally used yellow or red glass to minimize the effects of light that is not used in the process. The author discusses the discovery that the maximum intensity for the reduction of silver chloride by light is sometimes found in the ultra-violet and sometimes in the violet, and often even in the blue. Overall, the book explores the complex relationship between light and silver compounds, providing insights that have shaped the field of photography.
