Stephen Dalton

Stephen Dalton (born 1937) is an English wildlife photographer and author. He is known for his pioneering work, from the early 1970s onward, in high-speed nature photography. He was the first person ever to record pin sharp images of insects in flight.His work covers a wide variety of animals: from amphibians and birds to mammals and invertebrates.

Dalton was born in Surrey in 1937 and from a young age was an enthusiast for nature and photography. His father, a Royal Air Force officer, had been a bird photographer, and he had a godfather who collected butterflies, moths, and beetles. In the early 1960s he took a full-time photography diploma at London's Regent Street Polytechnic, about which he later recalled, "I had some of the happiest days of my life studying something I became fascinated by".

Dalton's first published article was in Geographical, the magazine of the Royal Geographical Society.He went on to supply images to the Natural History Picture Agency (NHPA) run by the entomologist L. Hugh Newman, whom he had met one day while out chasing wildlife with his camera. Later, when Newman retired, Dalton bought the business, and his NHPA became the UK's premier nature photography library. Dalton sold the agency in 2006.

Dalton started his work on insect photography in the early 1970s, before infrared beams or lasers, using a custom-made arrangement of lenses and mirrors, and a custom-made high-speed shutter. Working with an electronics specialist he devised a flash tube/capacitor combination which provided the required combination of high-power flash and extremely short flash duration. After two years of experimentation he was able for the first time to obtain sharp photographs of insects in flight.

Dalton's first full-colour book, Borne on the Wind (1975) took nature photography into new realms, with photographs that showed for the first time insects captured in free flight.

Dalton continues to live with his wife in the farmhouse in Sussex where most of his work has been done. His latest book, My Wood (2017) is a study of a wood he has owned since 1998.

In 2015 the Society of German Wildlife Photographers (GDT) awarded Dalton the Fritz Steiniger Prize. The citation notes that "The results of his experiments in high-speed flash photography and his subsequent publications were landmark events in the world of photography and caused a great stir worldwide" and that "his work of fascinating intensity and striking beauty has set visual and artistic standards that are still valid today".

One of Dalton's insect images was chosen to be carried on NASA's Voyager spacecraft, as part of a series of records designed to convey something of the science and culture of mankind to possible extraterrestrial beings.
