In evaluating a film scanner, one should consider its dynamic range. How deep can a scanner reach in and pull out shadow details from a very contrasty slide, for example. What about one that might have been underexposed a bit as you tried to keep from blowing out highlights?
I've seen some dynamic ranges posted for certain scanners here and elsewhere, many appear to be measured figures. But for the Minolta DiMAGE Scan Dual III and IV, the posted figure is 4.8 (calculated). That figure appears to be the theoretical dynamic range for the bit depth of the capture. Of course this is not going to be its true range. Does anyone know the actual range of these scanners? How is dynamic range measured?
