Hello Tim,
I have done a lot of scanning but never seen this effect before. It looks like
a limitation of the scanner. Have you thought of using a camera on a tripod to
make copies of the original photos? You are scanning at 600dpi, but a decent
camera should be able to exceed that easily if the originals are no larger than
a postcard (150mm x 100mm). Just make sure the photos are evenly illuminated
and set the camera colour balance accordingly.

Hi folks,
i'm trying to digitalis a postcard composed out of 4 different photos (without
access to the original). To get the highest resolution possible i bought me a
scanner, but while working grate on normal paper, its got problems with that
glossy postcard-paper i would like to remove digitally. I scanned the postcard
once horizontally and once vertically in 600 dpi photo mode (see both layers).
I rotated one layer and positioned it roughly, but i am not in search for a
complex ai based filter that removes distortions by combining both scans in a
complicated way, the two layers is just to state my issue.
My question is, is there any filter i can use to remove this rainbow-like lines
in one of the layers and if so, how could i accomplish this things with gimp.
Ill try to attach the file (ca. 40.8 MB xcf file) here, if this dosnt work you
can download it here:
