DIGITAL ICE Technology
Your scanner includes both DIGITAL ICE Technology for Photo Prints and for
Film. The DIGITAL ICE (Image Correction and Enhancement) technology is
built into the Perfection 4990 scanner and works along with the included
DIGITAL ICE software. This combination of hardware and software lets you
scan, correct, and restore your photos in one easy step, without any compromise in
image quality.
With DIGITAL ICE for Photo Prints, your scanner examines your photo for
defects on the surface, such as scratches, tears, and cracks. It does this by shining a
second light source on your photo and storing information about the shadows
these defects create in a separate data space. It then uses this information to
remove the defects from your scanned image so you don't have to remove them
yourself.
DIGITAL ICE for Film uses a different method to automatically remove
scratches, dust, and fingerprints from your scanned image. During the typical
scanning process, information is gathered using red, green, and blue channels.
With DIGITAL ICE for Film, an additional infrared channel collects the defect
information for correction.
The results are truly amazing. Though it takes a bit longer to scan with DIGITAL
ICE Technology, the end results will save you time. The majority of the
painstaking work of removing scanned defects is done for you. Final touch-ups
can still be done in Adobe
