Alexander Murray and Richard Morse invented and patented the first analog color scanner at Eastman Kodak in 1937. Intended for color separation at printing presses, their machine was an analog drum scanner that imaged a color transparency mounted in the drum, with a light source placed underneath the film, and three photocells with red, green, and blue color filters reading each spot on the ...
The OneScanner was a series of flatbed scanners marketed by Apple Computer during the early 1990s. The original OneScanner model was introduced in 1991 to replace the earlier Apple Scanner, offering 8-bit (256 shades) greyscale scanning. [1] It was joined by the Color OneScanner the next year, [2] and a series of updated models followed. The ...
The wider the angle, the larger the area the scan covers—but the more difficult it is for the scanner accurately track its movement due to physical limitations of the scanner mechanism. For example, a 20 degree angle provides a 3.5 metre scanned area at a distance of 10 metres from scanner to screen.
Image and Scanner Interface Specification (ISIS) is an industry standard interface for image scanning technologies, developed by Pixel Translations in 1990 (which became EMC Corporation's Captiva Software and later acquired by OpenText). [1] ISIS is an open standard for scanner control and a complete image-processing framework.
A film scanner scans original film stock: negative or positive print or reversal/IP. Units may scan gauges from 8 mm to 70 mm (8 mm, Super 8, 9.5 mm, 16 mm, Super 16, 35 mm, Super 35, 65 mm and 70 mm) with very high resolution scanning at 2K, 4K, 8K, or 16K resolutions. (2K is approximately 2048×1080 pixels and 4K is approximately 4096×2160 ...

Renting studio time at Nash Editions, Curran captured "scannograms" of objects from 1993-97.
