[Leica] Coolscan 5000 hi rez causing "grain" Rich Pinto sees grain on his Imacon, we would all like to know if true.

Simon,
I think that most of the "grain" is grain aliasing.  I suspect that
depending on the scanner the same film will show different grain
patterns.
That was certainly the case with a negative that Jim scanned for me.

Another example possibly is my last batch of Neopan 1600 I ran in Xtol
1:2 instead of my normal 1:3.  The negatives appeared the same through a
10X loupe but scanned much finer grained.  I don't think that 2.5
minutes less development time radically changed the grain structure of
the film: however, the slight difference was enough to not show up as
"grain" on my scans.

As to the "Luminous Landscape" article, I wouldn't put much stock in it.
I've been scanning Fuji films at 3600 to 4000 dpi for years and
routinely spot at 200 to 300% magnification.  I don't see what the
author sees.  Possibly the scanners I use have a much sharper plane of
focus, possibly it is just an anti Fuji rant.

Rich has been scanning with very hi resolution Imacons for a while.
Hopefully he could chime in with any observations.

I,m still wrestling with scanning so beforehand sorry for idiotic
questions.But do you feel that hi rez scanning sometimes makes low light
exposed film more grainy?I wondered if you scan low rez if you ever see
the grain .

p.s. thanks for earlier advice
