Used in advanced mode with the accompanying software SilverFast SE Plus 8, I get, at best, and after laborious rework that dull free images modeled. This is roughly in the printed photo quality screen on newsprint! Any attempt to improve things even more by playing on the contrast, saturation and color only causes unsightly distortion.
With the most difficult slide, such scenes shot under overcast, the scanner will hold authority over the lighter parts or the overcast sky, poorly restores the middle parts and the dark parts literally killing. Many details disappear. Tools levels and curves are helpless and merely produce distortions of contrast and color really horrible. A grain much higher than there actually has on the concerned photo appears (?). The multi-exposure improves, unfortunately, very few things ... (Yet I reviewed the TIFF output, so no losses!)
Very surprised by this poor result, I tried to photograph the same slide directly in a viewer, the front lens had been removed (because of its aberrations). The AFN is a compact Canon Powershot A650 IS is set on Macro position. After a fairly simple balance of brightness, contrast and color using the tool "curves" of free software GIMP, I get quickly and easily infinitely better pictures: bright, well detailed with good modeled and natural colors ...
Moreover, the scanner driver and the SilverFast software can be installed without problems under Windows 7. Documentation is pleasant, written in good French, but far too superficial! Aids are included in the advanced SilverFast features, but are not video subtitled in English. (They are therefore unusable for all who are unable to follow a conversation in English.) In addition, the so-called in French glossary, with a beautiful French flag on its front page, is actually in ... English, thankfully easy enough to read!
Also note that the tool "curves" SilverFast is very painful to use because of his nine points imposed from the start. Worse, the two end points can only be moved vertically and horizontally not!
IN SUMMARY. The dynamics of this scanner is too poor and too superficial documentation. That's a lot of "too much" to be a sensible unit of that level! I give up ...
