For color scanning the built-in software supplied automation for my feelings are not particularly helpful, well-covered manual settings lead on here ever. The dirt and error correction, however, gives good results. For my taste, the device by default, the supplied software scans but still clearly too bright, but can be adjusted. It depends here just overall a lot of material to be scanned from.
Significantly, however, is to complain about the quality of black and white scans. This shows in the dark areas enormous noise and otherwise the scanner detects the brightness values are not correct. The results in the area to be at best an assessment compose the subject on the screen. Archiving and even digital processing not worthwhile in my opinion. With photo chemically produced results, the scans can absolutely not be measured in any case.
Overall not a bad device, for S / W enthusiast but not a recommendation, which is why two star deduction.
Addendum of 09/01/2015
After meanwhile intensive use and familiarization with the equipment I have found that I was able to again significantly improve the quality of black and white scans, as I have the B / W negatives scanned in color mode. With the method of the scanner gives very good results.
