When I archive full data(without GEM). So I do not use GEM of Nikon scanner.
At post-scan stage, If needed, I use some s/w tool to remove the grains. In
future, if somebody comes up with a
tool that removes grains more efficiently(without or hardly loosing sharpness)
then I can run it on my archived data.
So, I would suggest using GEM tool at post-scan stage instread of scan stage.
In my macro shots, I do see the reduction in the sharpness due to GEM. I have
decided to stick to 100ASA
and avoid using GEM.
Thanks
Ramesh

Thanks Ramesh.
>From my very limited experience with NI demo (comparing JPEGs :-( )
one image showed a very slight difference in sharpness giving an edge
to NI (while producing about the same level of smoothness), while on
several others I wasn't able to distinguish any discernable difference
in terms of sharpness. And yes, GEM is considerably faster then NI.
I think I'll borrow a PRO version from the friend of mine and will run
a real test on TIFFs.

Alex
