[Leica] Scanning Software

[pklein at 2alpha.net (Peter Klein)]

This has been precisely the problem I have with CanonScan and the 
FS-4000.  Use the Canon software, and the highlights and shadows get 
clipped.  Use Vuescan, and all the dynamic range of the negative is 
available.  It happens with color negatives as well as B&W, and whether I 
scan 16-bit or 8.

One trick I've heard others suggest is to scan the B&W neg as a 
transparency, and then invert in your image editor.  I haven't tried this 
with CanonScan yet, and it is unnecessary in VueScan.
