Abney was born in
Derby, England, to a clergyman father. He attended Rossall School, the Royal Military Academy, Woolwichand joined the Royal Engineersin 1861, with whom he served in Indiafor several years. Thereafter, and to further his knowledge in photography, he became a chemical assistant at the Chatham School of Military Engineering.
Abney was a pioneer of several technical aspects of
photography. His endeavors in the chemistryof photography produced useful photographic products and also developments in astronomy. He wrote many books on photography that were considered standard texts at the time, although he was doubtful that his improvements would have a great impact on the subject.
Abney investigated the blackening of a negative to incidental light. In 1874, Abney developed a dry photographic
emulsion, which replaced "wet" emulsions. He used this emulsion in an Egyptian expedition to photograph the transit of Venusacross the sun. In 1880, he introduced hydroquinone. Abney also introduced new and useful types of photographic paper, including in 1882 a formula for gelatin silver chloridepaper.
Abney conducted early research into the field of
spectroscopy, developing a red-sensitive emulsion which was used for the infrared spectraof organic molecules. He was also a pioneer in photographing the infraredsolar spectrum (1887), as well as researching sunlightin the medium of the atmosphere.
Abney invented the "
Abney Level", a combined clinometerand spirit level, used by surveyors to measure slopes and angles.
