Ferdinand Hurter

Ferdinand Hurter ( born March 16, 1844 in Schaffhausen, † March 5, 1898 in Widnes ) was a Swiss chemist and photography theorist.

Life

Hurters parents are art bookbinding Tobias Hurter and his wife Johanna, née Oechslin. He grew up in Schaffhausen, goes to school there and from 1860 in Winterthur for teaching in the fabric dyeing Jänike. He studied chemistry at the Polytechnic in Zurich and received his doctorate in Heidelberg. Hurter 1867 draws to England and learns at Gaskell Deacon & Company ( later Imperial Chemical Industries) in Widnes know the engineer Vero Charles Driffield ( 1848-1915 ). It was a specialist of the Leblanc process for the production of soda and developed with Henry the Deacon process for the production of chlorine gas. In 1886 he became director of Imperial Chemical Industries Ltd.. Moon Division.

1871 married Hannah Garnett Hurter from Appleton in England.

Work

Hurter and Driffield develop together sensitometry and densitometry. 1890 published in the Journal of the Society of Chemical Industry their realization that a photographic layer is blacker the more, the more light is applied to it. This theory and its graphical representation in the characteristic curve (also density curve or Hurter - Driffield curve) simplify considerably as a result the photographs. A now famous quote from him is: " The creation of a perfect photographic image is art, creating a perfect negative is science. "
