Film Automatic Retouching And Enhancement
Infrared cleaning is a technique used by some film scanners and flatbed scanners to reduce or remove the effect of dust and scratches upon the finished image scanning, scan. It works by collecting an additional infrared channel from the scan at the same position and resolution as the three visible color channels (red, green, and blue). The infrared channel, in combination with the other channels, is used to detect the location of scratches and dust. Once located, those defects can be corrected by scaling or replaced by inpainting. Method The three color dyes in typical color film emulsions are largely transparent to infrared light, so the infrared image is almost uniformly clear, unlike the RGB images. On the other hand, dust absorbs and scratches scatter the infrared. Any dust spots or scratches appear as dark marks in the infrared, making them easy to find and compensate for. Pixels that are partially occluded (for example, the dust only obscures a small portion of the pixel) ...

Film Scanner
A film scanner is a device made for scanning photographic film directly into a computer without the use of any intermediate printmaking. It provides several benefits over using a flatbed scanner to scan in a print of any size: the photographer has direct control over cropping and aspect ratio from the original, unmolested image on film; and many film scanners have special software or hardware that removes scratches and film grain and improves color reproduction from film. Film scanners can accept either strips of 35 mm or 120 film, or individual slides. Low-end scanners typically only take 35mm film strips, while medium- and high-end film scanners often have interchangeable film loaders. This allows the one scanning platform to be used for different sizes and packaging. For example, some allow microscope slides to be loaded for scanning, while mechanised slide loaders allow many individual slides to be batch scanned unattended. Some software used to process images scann ...

LaserSoft Imaging
LaserSoft Imaging AG is a software developer designing image processing software such as SilverFast for scanners and large format printers. The company's headquarters is located in Kiel, Germany, north of Hamburg, and another office in Sarasota, Florida, United States. History 1986–1990 LaserSoft Imaging was founded in Spring 1986 by the physicist Karl-Heinz Zahorsky, the president of the company today. LaserSoft Imaging became an early adopter of color- and image processing on the Macintosh. It was the first company to distribute video digitizers, such as Pixelogic's 'ProViz' and Truvel's 'TrueScan', the first professional color scanner for the Macintosh, which was first shown at Hannover trade fair CeBIT in 1988, to which LaserSoft Imaging was invited by Apple Computer. 1990–2000 In 1991 LaserSoft Imaging became a registered GmbH and moved into a large Prepress house to help in setting up color reproduction on the desktop and to link Chromacom systems to Ma ...

Hamrick Software
VueScan is a computer program for image scanning, especially of photographs, including negatives. It supports optical character recognition (OCR) of text documents. The software can be downloaded and used free of charge, but adds a watermark on scans until a license is purchased. Purpose VueScan is intended to work with a large number of image scanners, excluding specialised professional scanners such as drum scanners, on many computer operating systems (OS), even if drivers for the scanner are not available for the OS. These scanners are supplied with device drivers and software to operate them, included in their price. A 2014 review considered that the reasons to purchase VueScan are to allow older scanners not supported by drivers for newer operating systems to be used in more up-to-date systems and for better scanning and processing of photographs (prints; also slides and negatives when supported by scanners) than is afforded by manufacturers' software. The review did not ...

Digital ICE
Digital Image Correction and Enhancement (Digital ICE) is a set of technologies related to producing an altered image in a variety of frequency spectra. The objective of these technologies is to render an image more usable by Fourier or other filtering techniques. These technologies were most actively advanced in the 1960s and early 1970s in the fields of strategic reconnaissance and medical electronics. The term ''Digital ICE'' initially applied specifically to a proprietary technology developed by Kodak's Austin Development Center, formerly Applied Science Fiction (ASF), that automatically removes surface defects, such as dust and scratches, from scanned images. Technology The ICE technology works from within the scanner, so unlike the software-only solutions it does not alter any underlying details of the image. Subsequent to the original ''Digital ICE'' technology (circa 1989), which used infrared cleaning, additional image enhancement technologies were marketed by Applie ...

Minolta
was a Japanese manufacturer of cameras, lenses, camera accessories, photocopiers, fax machines, and laser printers. Minolta Co., Ltd., which is also known simply as Minolta, was founded in Osaka, Japan, in 1928 as . It made the first integrated autofocus 35 mm SLR camera system. In 1931, the company adopted its final name, an acronym for "Mechanism, Instruments, Optics, and Lenses by Tashima". In 2003, Minolta merged with Konica to form Konica Minolta.

Kodachrome
Kodachrome is the brand name for a color reversal film introduced by Eastman Kodak in 1935. It was one of the first successful color materials and was used for both cinematography and still photography. For many years, Kodachrome was widely used for professional color photography, especially for images intended for publication in print media. Because of its complex processing requirements, the film was initially sold only with the cost of processing; independent photography stores were prohibited from developing Kodachrome. To develop the film, customers had to mail it to Kodak, which would then send the developed film back as part of the purchase price. In 1954, the U.S. Department of Justice found that this practice violated antitrust laws by being uncompetitive. Kodak then entered into a consent decree, requiring the company to offer Kodachrome film for sale without the development fee, as well as license Kodachrome development patents to independent photography stores. Kodak ...
