I also got the issue, on OS X Lion, built from git (v1.0+823~gcabfe1f).
Pictures were taken with a Canon S95.

Still happens on Ubuntu 12.04, with packages from extra and darktable-release-plus ppa (i.e. darktable 1.0.5, libraw 0.14.7...) with RAWs from Sony NEX-C3. Do you need the input/output files?

  • Status changed from New to Incomplete
  • % Done changed from 0 to 20
  • Affected Version set to git development version

Does this only happen with old HDR DNGs or also with newly created ones? Please also test with the unstable PPA.

#6 Updated by Torsten Bronger over 5 years ago

I can reproduce this with the current git-master. With Sony NEX-7 ARWs.

Any news on this? Does this still happen? Jo, what do you think?

#8 Updated by Torsten Bronger almost 5 years ago

I can reproduce it with current git master.

Do you need other example images? I haven't tried the attached ones.

Hey guys,

I found your thread while searching infos about the problem with the green tint.
When I created a hdr with darktable 1.4.1 on Ubuntu 12.04 (32bit). I had the same problem. Have you got any infos about this problem?

Do you need some sample pictures?

The camera is a Panasonic Lumix DMC-LX7 an it creates pictures in rw2 format.

Thanks a lot for your help in advance.

There were some changes in the HDR merging code, so hopefully this is fixed.
Could you please test and report any (new?) issues if you could find them.

#15 Updated by Torsten Bronger almost 4 years ago

The HDR feature is still not producing pleasent results for me (e.g., contrast depending on zoom level, way too dark, worse dynamic range than in a single image). But at least, there is no green tint anymore as far as I can see.
