Editing Infrared (section)

=== Cleaning ===

[[Infrared cleaning]] is a technique used by some [[motion picture film scanner]]s, [[film scanner]]s and [[flatbed scanner]]s 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]].<ref>[https://web.archive.org/web/20110107163528/http://motion.kodak.com/US/en/motion/Products/Lab_And_Post_Production/dice.htm Digital ICE]. kodak.com</ref>
