RE: filmscanners: Stellar ghosts and Nikon Coolscan IVED (LS40)



Harry - maybe this is a bit obvious, but why don't you write to Nikon with 
a sample and ask them what they suggest?  They may not be the world's best 
at customer relations (perhaps because they are trying to avoid a "jaggies" 
fiasco) but IME they always answer emails I send to ...

Nikon - Digital Imaging <digitalimaging@nikonincmail.com>

It seems to be a real problem you have there, and one which may turn out to 
be fixable or may be something that Nikon need to look at.

Best of luck,

Julian
