[filmscanners] RE: Nikon LS-40 vs Polaroid SS4000

["Hemingway, David J" <HEMINGD@polaroid.com>]

The differences in the light source are really NOT exaggerated and it is not
a Nikon/Polaroid issue. It is a LED vs. Fluorescent/cold cathode issue.
I actually wondered that myself until I did the scans. At that time it was a
SS4000 vs. a LS2000 and there is a substantial difference in dust shown.
Using a LED light source also produces more contrasty scans. There are other
issues that many claim is caused by the LED light source.

>>I'm sure that Digital Ice is great as it has so many passionate
advocates. I've never felt the need for it on my SS4000.

My workspace is not even close to a clean room. I take reasonable
care of my slides and negatives. I don't have to spend a lot of
time cleaning dust spots and scratches on my files.

I wonder if the different light sources and imaging paths on the
Nikon & Polaroid scanners account for some of the dust and
scratch sensitivities that their users encounter?<<


That's what some people say, and the Polaroid people like like to emphasize
this, but I think the differences between the light sources are exaggerated.

I try to use the best labs in town, but I still find occasional embedded
specs of dust, as well as the odd surface defect. Even if you maintain a
clean scanning environment, most people end up having to touch up the
majority of slides anyway.

I find that ICE is a real productivity tool. It does a very thorough job
without any negative consequences, other than additional scan time. ICE
processed images also have a smoothness that is very appealing.
