[filmscanners] RE: Minolta Dimage Scan Elite - any users here?

Ok Art got your point.
The dICE indeed cannot be used with natural B&W films as you correctly
pointed about, but since I almost never shoot real B&W anyway I don't care
this limitation.
As about Nikon's inherent dust exaggerations due to the particular lighting
source, I've heard about it many times and perhaps there is some truth in
that.
In fact, my home image working environment isn't exactly sterile and usually
a lot of dust accumulated around (as in most homes though :-) ) I found dICE
invaluable for saving a lot of time which I just don't have.
Moreover, as I said so far I wasn't able to figure out quality loss due to
dICE processing on regular setting and IR scan time premium is not something
I would consider at all (adds about just a few second).

However it would interesting to see how, say, SS4000 would cope with average
dirty originals
diminishing thee defects.

Simply put, the NIkons make some of their own problems.  They exaggerate
surface defects (dust, scratches, dirt, etc) due to the lighting source
(collimated LED lighting) so you basically MUST use ICE or have
perfectly clean and unhandled film.  Some other scanners do not cause
this problem, and so ICE is not really necessary.  dICE was originally
only available for large industrial/commerical scanners.  After Nikon
got so many complaints about the amount of dust/defects that they showed
when images were scanned, they needed dICE to survive, especially as the
scanner resolution was improved upon.

dICE is a brilliant solution, and it has its place, especially for
severely damaged or dirty images, or for fungus damage, but it comes
with a cost, both literally and otherwise.

The problem is that true black and white films do not work with dICE at
all, because silver is opaque to IR.  So, with black and white, you
simply cannot use dICE, and must hand spot.  With some other scanner
brands, the problem of exaggerated surface defects simply doesn't exist,
either with color or B&W film so ICE isn't really an issue, and black
and white scans easily.

This is why I suggest against people considering Nikon scanners if they
shoot a lot of true B&W film (as opposed to C-41 chromagenic black and
white which is actually a film which has its silver removed during
processing, like color negative film.)
