[filmscanners] Vuescan colour neg problem

["Tim Atherton" <tim@KairosPhoto.com>]

Hi All (Ed...),

I'm having problems scanning some 4x5 colour negs on my Epson 1640 using
Vuescan.

They are  Portra 160 and Fuji NPS.

I have worked a good setup with the colour settings, brightness etc, using
the neg profiles in VueScan.

BUT I'm getting banding/scanner artefacts in the blue skies. Now, I know the
blue channel on these flatbeds can be noisy, but I don't get this problem on
transparencies, or if I scan the neg as a transparency and try and convert
it in PS (but then it's very hard to get rid of the orange mask and get
decent colour correction).

Any ideas anyone...?

Thanks

Tim A

PS - using latest VueScan and PS6
