Re: filmscanners: Vuescan sharpening ( reflection on sharpening in general)

I don't totally disagree, but I seem to get (slightly) better results by
using the Sharpen filter *after* retouching/spotting--probably because I'm
more forgiving of a little "softness" than of all those white spots on old
film! :-)

Also, because I'll tend toward using PS's Dust filter to get the little
stuff (unless the subject is kitty-cats), which is itself a bit of an
unsharp mask. I've found that if I Sharpen early on, grain-aliasing can be
the headache. Then I have to use Despeckle, and "here we go again." Too many
filters is not so good for the picture or your outlook.

Probably there *isn't* a "one size fits all" method for every picture (there
certainly isn't for the ones I'm doing), and the old computer addage, "Save
Early and Save Often" coupled with a bit of experimenting is probably still
the best advice. :-)

And I totally agree with Erik--no flame wars!

Best regards--LRA
