A device that scans a photographic film directly to a computer is called a film scanner; there is no need for any intermediary printmaking or any other equipment. Film scanners provide several advantages such as direct control of the photographer over aspect ratio and image cropping. Some models also come with specific software or paraphernalia that helps in removing scratches, film grain or enhance the color duplicate of old negatives. Film scanners generally accept 35 mm strips or 120 film and individual slides. This functionality allows the scanning platform to be utilized for various sizes and packaging.
They may seem insignificant and but dust and scratches can be a huge problem. A Film scanner has resolution greatly higher over a regular flatbed scanner. Usually it has between 2000 samples per inch (spi) and 4000 spi or more. With these resolutions, dust and scratches on the film are not anymore negligible, quite the opposite. Tiny flecks of dusts can result to unclear group of several pixels. Various techniques and technologies have been developed in order for film scanners to read films strips without too much difficulty such as median filter, infrared cleaning, and the old fashioned way of film restoration. Film scanner makers typically have their own name or label for such technique. Kodak launched ICE and is licensed by Nikon , Epson and Microtek. Canon produced its very own FARE (Film Automatic Retouching and Enhancement) technology.
