I just did a comparison between ICE and Photoshop's Dust & Scratch Filter.
I was hoping that the Photoshop filter would work, but, the results favored
ICE.  Viewing an image scanned without ICE, I applied the Photoshop Filter
at a variety of settings.  It was my impression, based on what I saw using
'Preview' at a variety of settings, that the Photoshop Dust & Scratch Filter
is practically worthless.  Using very sharp images and using the "Print &
Acutal Pixels' Views, it was my impression that any softening of spots and
dust resulted in an extreme softening of the image.  There is no question
but that Digital ICE is much, much more effective at dust and spot removal
while at the same time it softens the image much, much  less that does the
Photoshop Filter.
