[filmscanners] Dynamic range question
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?
