Re: filmscanners: Dust in Sprintscan 4000?

Rick Samco compared these two scanners here:

Up until I saw this I was quite keen to trade my Artixscan 4000T (SS4000
clone) for a Nikon largely for ICE. After all de-spotting is a nightmare
except on very clean images.

I have yet to find any thing other than a clone tool that removes the dust
spots from my A4000T scans. I have discovered however that by not looking at
your images at all before scanning (I use slides) you can minimise the
de-spotting to about 5 minutes max. Obviously this isn't much good for old
slides. I have some family slides ([not] cared for by my Dad) which it would
take many hours to clean up. I only have a 17" monitor and have to look at
about 40 screen fulls to check one image for dust spots, but if you have a
huge monitor this is probably much easier.

On examining Rick's samples I decided that the Nikon seemed to have very
slightly better sharpness and detail but turning on the ICE made it very
slightly worse. This was reasonably acceptable, but the Nikon seems to also
produce very grainy scans and the only cure is GEM which softens images
quite badly. I have quite enough trouble with grain so I decided to stick
with the A4000T.
