Digital Ice is what we have built into our Slide & Film Scanners to make a Slide look the best it can, before you fix what's left over in Adobe PhotoShop.
BTW: Sicience Fiction Software.com is now selling Digital ICE as plug-ins for PhotoShop. Since the Program is built into our scanners, that is the only time we can use it now.
As for fungus & slides, we use PEC-12 to clean all the slides we scan, dirty Negatives are cleaned also before scanning if needed, I don't want to save time today, & have to learn how to tear down, & clean the scanners if I don't have to.
The time it saves me in PhotoShop is realy worth the extra money I have to pay for the scanners. It's not cheap, so you will have to decide how much you will use the process, & are you getting paid to use it. We do DVDs from Slides, Film & Pics, so the time saved in Photoshop, is pure profit
