I did those by creating "RAW" images with vuescan:

But when I import the images to darktable it seems not to be able to read
those. All I get is white frames with aspect ratio 3:2 but I see some EXIF
like scanner Manufacturer and Modell as well as date/time of the scan in
image information.
Any clue?
What darktable version are you using? Please open a bug report and
attach an example file. There's probably something specific to the
vuescan DNGs that rawspeed doesn't support.
By the way. Is there any particular reason for doing DNGs in this
situation? Do film scanners actually produce a bayer pattern? If they
produce RGB you're probably better off just producing a 16bit or 32bit
TIFF.
Cheers,

Hi Pedro,
I use the stable darktable 1.4.2 from Pascal.
Vuescan has been Software VueScan 9 x32 (9.1.14)
I attach the complete EXIF.
These are files I produced last year while converting to Linux and
darktable and non-destructive workflow from digital cameras and I
decided it would be a good idea to use darktable for my analog workflow
also.
In the meantime I did dcraw -T -4 -D *.dng to all the files and those
TIFF files are imported correctly and work fine.
I'll think about using TIFF output for the future. As far as I know the
scanner produces RGB, not Bayer.
