If you wish to use either of the dust and scratch removal features you'll find that unlike in SilverFast 6.x and earlier you may no longer use these features while creating HDR scans in SilverFast 8.įor Silverfast 8 SE that means that there is no useful way to create linear scans while using the dust and scratch removal techniques at all. ![]()
