The image on a negative is contrast compressed, which is why negative 
film has such a high exposure latitude, compared to slide film where the 
image is often contrast stretched to get a punchy, saturated result. 
Consequently, the scanner software must stretch (decompress) the 
contrast on the negative, which it does not need to do with slides. This 
process enhances minor defects on the film, such as dust and scratches, 
which would not be noticed on slide film.

I personally find white specs, as comes from dust on negatives, much 
more objectionable that black specs, which dust would produce on slides 
- but that is probably just me and not a general issue.

Every time you expose the film to domestic air it will be contaminated 
by dust particles that will stick to the film by static, and they can be 
picked up in the scan.

ICE is licensed by Nikon from Advanced Science Fiction.
FARE is an independently developed similar approach implemented by 
Canon.

People come and go from organisations all the time - it usually creates 
a lot of hiatus at the time followed by very little change in the long 
run.  Helpful as David was, I don't believe that he influenced the 
design or documentation of Polaroid scanners particularly, and certainly 
not in any way that cannot be achieved by others.
