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
I'm not sure if ICE can fully be implemented as a software solution. My understanding is that it uses a channel in the scanner to detect irregulaties on the surface of the film and correct them. Wonder how the pure software version will work.
I have actually tried using PEC-12 but looks the fingus on my slides cannot be effectively removed. In fact, the PEC-12 liquid leaves a white layer on my film. So I stopped using it now. My current Minolta Scan Dual III is quite useless against removing the fungus marks from the scans. The fungus marks are more subtle until viewed in full size. Wonder if anybody could let me try scanning my "fungified" film on their ICE-enabled scanner to see how effective is ICE against fungus marks.
