Ferdinand Hurter (1844–1898) and Vero Charles Driffield (1848–1915) were nineteenth-century photographic scientists who brought quantitative scientific practice to photography through the methods of sensitometry and densitometry.
Hurter & Driffield's actinograph.
Among their other innovations was a photographic exposure estimation device known as an actinograph.[1]
