The CanoScan 9900F Color Image Scanner has nearly all the features you could ever wish for to handle any scanning needs, fast and easily. Resolution as high as 3200 x 6400 dpi immediately identifies the 9900F scanner as a powerful tool. Scan previews in approximately 3 seconds and up to 48-bit depth for over 281 trillion possible colors confirm that this is the definitive scanner for professional-looking results. Connections for either FireWire or USB 2.0 Hi-Speed provide customers with rapid transfer rates of up to 400/480 Mbps - perfect for large files. The 9900F scanner is built to deliver spectacular scans all day long for your choice of photos, transparencies or negatives in a wide range of sizes: 35mm, medium-format or 4" x 5" - and photos or documents up to 8.5" x 11". To quickly and conveniently add negatives or slides to any project, a built-in 35mm film adapter scans up to 24 negative frames or 8 mounted slides at a time. Four external buttons make it easy for you to scan, copy, e-mail or file. Place your photo or film, press the external Scan button - and the 9900F scanner takes over from there, automating the entire process. For added ease-of-use, scan multiple images in one pass with Multi-Scan mode. The 9900F scanner includes a powerful suite of applications featuring Adobe Photoshop Elements 2.0. The 9900F scanner's built-in automatic retouching technology, FARE 2.0 (Film Automatic Retouching and Enhancement) is designed to automatically and precisely remove much of the dust and scratches that may appear on your original slides or negatives - so final scans of dusty and/or scratched film can look better than the original.
