Digital ICE is a technology that allows scanners to automatically identify and remove dust marks and minor scratches. Digital ICE performs a scan of the film with Infra-red (IR) light. Using the IR scan, the machine visualizes surface defects in the film, like dust or scratches, and then scans the film normally. Once both scans are completed, special software uses the IR defect map to replace the defective areas. The results can be a dramatic improvement from the original.
