RE: filmscanners: Best scanner software

I've used the SS4000 and LS-4000, and I'd agree that the Polaroid shows less 
dust than the LS-4000.  The common wisdom is that this is due to highly 
collimated light source in the Nikon scanner - it shows up every last speck, 
where the gentler light source of the Polaroid doesn't.  It's kind of like a 
condenser enlarger head vs. a diffusion head.  The scans are equally detailed 
from both.

Switch on IR cleaning in the Nikon, and the problem goes away, though you do 
trade off spotting time for longer scan times.  I use Vuescan with my LS-4000, 
and can see no appreciable softening of the image from the operation of 
cleaning algorithm, so I too use it all the time.

Thanks for the answer.
The SS4000 doesn't offer IR based ICE feature, so did you mean *always*
IR cleaning when scanning with your LS30 ?

BTW, I'm confused a bit by your claim of dust/scratches being less obvious
with higher resolution. My opinion was exactly opposite: more resolution
picks up more dust, due to
smaller pixels being used to achieve bigger resolution on similar physical
Am I wrong ?

I've made nice A3 prints on my Epson 1160 using scans at 2700dpi with a
Nikon LS30.  Scans on a SS4000 look bigger, but I'm not convinced that
there's a lot more detail in them.  I generally scan with Vuescan, and
*always* use Infra-red cleaning.  Infra-red cleaning saves hours of
spotting.  Dust and scratches are less obvious in SS4000 scans, so there's
less spotting anyway.
