Digital ROC should have no effect on defect removal and we specify that Digital ICE should be run first. Also, a note on Kodachrome; Digital ICE will work quite effectively on many (but not all) Kodachrome images. It is important to try it on your negatives. We may have given the impression in the past that it doesn't work because we feel it is important not to misrepresent our product. We'd rather say it doesn't work on Kodachrome at all then to imply it always works. There might be some feedback from this user community on the effectiveness of Digital ICE on Kodachrome.

Part of the ROC algorithm identifies what portion of each pixel belongs to each dye layer. When the scan includes IR, this information can be used to help separate the RGBI layers. Using this should help isolate dust from actual image content. Does anybody have a Nikon scanner and could they check to see if ROC+ICE actually does better than just ICE for removal of dust? Or is this just something that was mentioned in the patents and never implemented in the commercial software? If fully implemented, it might allow reasonable dust removal from Kodachrome slides.
