The Cromemco Cyclops was an all-digital camera introduced as a commercial product in 1975. Its design was published as a hobbyist construction project in the February 1975 issue of "Popular Electronics" magazine, and it used a 32×32 Metal Oxide Semiconductor sensor. Steven Sasson, an engineer at Eastman Kodak, invented and built the first self-contained electronic camera that used a charge-coupled device image sensor in 1975. Early uses were mainly military and
Kodak High-Speed Infrared at a street price of around $12 a roll at US mail order outlets. Despite the discontinuance of HIE, other newer infrared sensitive emulsions from Efke, Rollei, and Ilford are still available, but have differing sensitivity and specifications from the long-established HIE. With the discontinuance of HIE, Efke's IR820 film has become the only IR film on the market with good sensitivity beyond 750 nm. Kodak High-Speed Infrared Kodak High-Speed Infrared film, also known as Kodak HIE, was a popular black-and-white infrared photographic film from Kodak. The film is sensitive to the visible light spectrum (with decreased green sensitivity), infrared
