[filmscanners] Re: Color Misregistration (Especially PolaroidSprintscan 120)

["Arthur Entlich" <artistic-1@shaw.ca>]

The reason for this is simple, it does indeed over double the scan time
from 1:30 to 3:25 min.  The reason it seems less is because the dICE
process so slows the process (1:30 to 3:40) that the superfine mode
doesn't seem to make a big difference between the regular scan with dICE
and the super fine mode with dICE (3:40 to 4:30).  The dICE process goes
on in the background while the scanner is slowed down for the superfine
scan mode.

You also obviously have a quite fast computer based on these numbers.
