Digital ICE is equivalent to the "Defect Correction" function in Nikon Scan 2. Digital ICE does not perform equally well with all types of film. If you are using Kodachrome film, you may find that Digital ICE does not have the desired effect, or that there is an overall degradation in image quality when Digital ICE is in effect. We recommend you turn Digital ICE off when using black-and-white (color monochrome film excepted) or Kodachrome film. Restoration of Color (ROC) Digital ROC, a tool for digitally restoring colors lost through fading of the original media, is built in to 4000 ED and COOLSCAN IV ED film scanners. To use Digital ROC, turn the Enable Post Processing check-box on and then select the amount of correction to be performed using the Digital ROC slider or by entering a value in the text box to its right. The default setting is "5"; move the slider to the right to increase the effect of Digital ROC, or to the left to decrease its effect. Choose "0" to turn Digital ROC off. To view the results in the Natural tab prior to scanning, click the Redraw button. Because of the complexity of the processing involved, scans performed using Digital ICE requires longer scanning times. Reference:The Tool Chest Post-processing using Digital ROC and Digital GEM is not available with the LS-2000 and COOLSCAN III. 52
