I have been using the Applied Sience Fiction (ASF) - Kodak Digital ROC filter a lot in the past. So far I did not find a comparable filter. There are scan programs that try to solve the problem, but they only work while you scan. So you can not use them on an existing file. And most of the time they are inferior to the AFS-Kodak algorithm. This is strange considering how old Digital ROC is. I know you have a coloring app but that is not the same, you do not retrieve the original colors. Digital ROC does this most of the time in a remarkable way. Kodak stopped all sales & support.
