Vuescan is, I believe, primarily a photo scanning application. Considering the range of scanners it supports, I think it does a credible job. I’ve scanned 1000’s of slides and negatives with Vuescan and, while it has its quirks, I thought it did a fine job.
I have a 20 (yes, 20) year old Agfa scanner that still helps on occasion for some documents even though I very rarely use it now. But it does come in handy at times. Yes, VueScan is clunky as hell to use and ugly as sin, but kudos to it to be able to help me use a 20-year old device when I need it. Wouldn’t use it on everyday workflows though.
