I am using a Minolta Dimage Scan Elite 5400 film scanner to make high resolution (ie at 5400 dpi) scans of my slides and negatives. I have noticed that when I use the multisampling facility (which I have to because I have a lot of night scenes and scanning them without multisampling leads to digital noise in shadow regions) it leads to a softening of edges and a loss of detail. Is this supposed to happen? Do I have a possible fault in my scanner? Or is it one of those situations where some sort of trade-off is unavoidable? Do other scanners have this problem?
