Re: filmscanners: scanner dilemma

This is very-slightly Off-Topic, but I don't think I'm alone in welcoming Ed
Hamrick back to the Filmscanners List. We've missed your insightful
comments, which really do add a lot to the discussions.

Best regards--LRA

Grain removal has nothing to do with the infrared channel.  The
reason GEM and ROC only work with certain scanners is because
only these scanner manufacturers have paid money to ASF to
license these algorithms.

Note that GEM and ROC are included in the Minolta Scan Multi II
software, and that this scanner doesn't have an infrared channel.

VueScan uses different (and I think better) algorithms for grain
reduction and color restoration than GEM and ROC.

The new Canon D2400 flatbed and FS4000 film scanners have
their own version of infrared dust removal (FARE), but Canon
isn't advertising that they have any grain reduction software
or color restoration software.
