Subject: [filmscanners] Tramlines on Minolta Scanners - Photoshop Mask
For anyone that's interested, this is a technique I've used to combat
tramlines on
Minolta scanners which seems reasonably effective. As I said in my last
post It only
works with tramlines which are caused by black point mis-calibration, ie the
ones that
only appear in the shadows, but not in the mid-tones or highlights, and
which are always
in the same CCD position. It won't deal with tramlines caused by dust etc
in the
lightpath...
