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

["Michael Moore" <miguelmas@qwest.net>]

No flames here... But, every book I've read on working with PhotoShop (and I
have more invested in books than I care to think about) states that the
application of sharpening (actually Unsharp Mask in PShop) should be the last
thing you do before printing the image on the inkjet or whatever printer you
use... If I  going to send the PSD or TIFF or JPEG to a regular printer (as in
newspaper or magazine), I never sharpen or Unsharp Mask the image... I make sure
the graphics person or printer knows it is not sharpened, as they generally
apply some sharpening as a matter of course on all the images they print... Try
an experiment and see what happens to your image if you sharpen it right after
scanning, then later after doing your corrections... I guarantee the results
will not be a pro quality image...
