The final part in this three-part series on Orthochromatic Photography, describes how scientists used new light and color measurement techniques to characterize photographic plates and determine the precise specifications required for color photography and color printing. Many of the concepts developed during this period can be seen reflected in the work of the CIE that defined modern colorimetry decades later.

Orthochromatic Photography, Part 2, traces the graphic arts community’s quest to understand the nature of photographic materials and develop a system for accurate light and color measurement. We can clearly see the origins of what developed into modern spectrophotometry, densitometry, and the CIE system of Colorimetry, through the work of William Abney, Leon Warnerke, and others.

In 1936, Alexander Murray published a simple equation that would have a profound impact on the printing industry. This simple equation, first suggested to him by Edward Roy Davies, and now known as the Murray-Davies equation, was a key development in the quest to create standardized tone reproduction processes in a world where printing was a much a craft as it was a manufacturing process.
