Using the Epson software, I am having real issues with the ICE dust removal component. Below are two crops from similar photos, one scanned with the ICE dust removal and the other without. The problems with the dust removal are very obvious. I used the Speed setting rather than Quality, but this has made no difference in the past.
For Matt and others: surely this is not to be expected? Can you think of anything I am likely to be doing wrong to get this result?
I get the same sort of result irrespective of using USM, and the size of the target scan.
