First of all, I'm taking the liberty of copying comp.periphs.scanners
in this reply. It's more mainstream; this group you started with is
little frequented.

I'm guessing that you are correct about the standard/professional
versions of VueScan, but I don't know this for a fact. I haven't kept up
with VS for a while as haven't really scanned much of anything in couple
years, 'cept for quickie flatbed copy stuff.

At any rate, I have Nikon 2000, and just used Vuescan "pro" 8.3.68,
saved as 64 RGBI tiff, and photoshop CS 8, certainly sees IR channel (as
"alpha 1), and certainly sees all the dust therein.

HTH,
