History

#1 Updated by Pascal de Bruijn about 7 years ago

  • Affected Version changed from 1.0.5 to 1.1.0

It seems the D1X is unsupported by RawSpeed, at which point Darktable falls back to LibRaw which seems to be failing as well :(

#2 Updated by Pascal de Bruijn about 7 years ago

http://imaging.nikon.com/lineup/dslr/d1x/index.htm

Apparently the D1X has a rather bizarre sensor:

"5.3 effective megapixels for 4,024 x 1,324-pixel images"
"10MB output of 4,016 x 2,616 pixels with NEF (RAW) file using optional "Nikon Capture 4" Software"

#3 Updated by Pascal de Bruijn about 7 years ago

  • Status changed from New to Closed: won't fix

So, it appears the image needs vertical stretching after demosaic, which isn't implemented in Darktable. And it seems the D1X is one of the few (if only) camera's that requires something like that.

The workaround would be to convert the image to a 16bit TIFF using dcraw like so:

dcraw -v -w +M -H 2 -o 1 -f -6 -W -g 2.2 4.5 -T NIKON_D1X.NEF

And import the TIFF, after which you can still enable the Basecurve(Nikon)/Sharpen/other modules in Darktable.

#7 Updated by Roman Lebedev over 5 years ago

  • % Done changed from 20 to 100

I implemented scalepixels iop, which is in master as of now.
So this should be fixed.
