LaserSoft Imaging

Using HDR and Lite Ice with 66 negs I started getting some severe and BIG artifacts espicially in highlights. Looks like big corruption. This corruption goes away with Quality ICE but there is so much dark to light edge erosion that is it's own problem.

I prefer Lite ICE both because it softnens very little, (Quality ICE softens a lot) and because it does not introduce edge erosion.

Why is HDR and Lite ICE causing the BIG corruption?

The film is not Kodachrome, just Konica Professional 400 which is in the negafix list. This happens with "for HDR" checked or not.


Now I just found another variable, with a crop of the center of the same frame, no setting changed at all the problem of BIG corruption is gone but when the full frame is scanned the issue returns.

And another variable, the frame next to it does do this. The main difference is the one with problem has a big old white sign, an old gas station, and the problem free one does not have any big areas of highlights. Also the one with the big white area only had the problem if the whols frame was scanned but with the center crop there was no issue.

And a final non-HDR scan of the whole frame had the problem so it was not HDR specific. It is Lite-ICE that specific image.

What could be happening?

Dear newindustar,

ICE is completely handled by the drivers which come from your scanner's manufacturer.
You maybe want to check if newer drivers are available.
You can also contact us through our support assistant for further help.

I did not realize I had a reply and I have been away for a bit. My ICE saga continues nonetheless. I have to report those huge artifacts have only happened to me using Konica Professional 400 in 220. I don't have it in any other format. Could it have to do with the thinner base of a 220 film? I don't have any other 220 at the moment. I don't fully understand where ICE is hardware and where software but EpsonScan of Silverfast both have the same issue with that film on Lite ICE V700. v**s**n does not, I have to admit it points to a driver issue.

Dear newindustar,

ICE is most likely to cause artifacts if the infrared channel of the scanner is disturbed by the filmemulsion.
But to say more abaout those artifacts I would need to see a sample scan.
