  • Silver Halides an overview ScienceDirect Topics

    Silver halides are naturally sensitive to ultraviolet and blue light only. That it is possible to photograph objects of all colours is the consequence of the discovery, made in 1873, of the means of extending the sensitivity of silver halides into regions of the visible light spectrum beyond the blue.
