You can also write in DNG format these days, though, and feed the file into
"standard" raw converters. I would assume there isn't much you can't do with
these files compared to the ones from a DSLR, apart from playing with the
Bayer pattern interpolation parameters, obviously...
I don't think any scanners create bayer mosaic output data. Vuescan's
DNG files are DNG encapsulated TIFF, so they are RGB files inside a
DNG container that can be edited with raw processing tools,
Well, DNG *is* TIFF, isn't it, in many ways. So I don't know about
"encapsulated".
But this was what I was trying to say, really - the Vuescan DNG does not
have mosaic data, so any demosaic/interpolation settings will obviously
have no effect, but they are hardly relevant anyway since you have true
RGB data already. Besides that, I should think that anything you can do
with a camera DNG file, you can also do with one from Vuescan.
which
arguably can do a better job for some things.
Exactly.
