Judging by the error message, in your case the library is loaded from some other install, and it looks like it might be not finding libexiv. You may want to cleanly uninstall and remove all previous darktable installs and then reinstall. It should pull in libexiv if it is missing, as that is one of the package dependencies. darktable 2.0.3 from the official Xenial repository works fine here on 16.04 (albeit on Kubuntu). ~# apt-cache policy darktable darktable: Installed: 2.0.3-1 Candidate: 2.0.3-1 Version table: *** 2.0.3-1 500 500 http://archive.ubuntu.com/ubuntu xenial/universe amd64 Packages 100 /var/lib/dpkg/status -- Šarūnas Burdulis http://math.dartmouth.edu/~sarunas signature.asc Description: OpenPGP digital signature

On 07/30/2016 05:35 PM, Michael wrote: > How do we use these things with dark table? I like very much the color balance, which I see in Olympus out-of-camera JPEGs, and I wanted to have a darktable style as a starting point for processing RAW. I used a similar GretagMacbeth color pattern to create a style using "color zones" module. That is, I took a picture of the color checker in direct sunlight and tried various settings on RAW to match the JPG. Color zones module manipulation produced the best result, though the match still wasn't perfect. The resulting style works very well on some scenes, but less so on others. Then I discovered IT8 target from Wolf Faust and this: http://www.darktable.org/2016/05/colour-manipulation-with-the-colour-checker-lut-module/ The latter is of course a much more systematic approach. It uses "color checker lut" module (as of today one has to use darktable compiled from git master) and a darktable-chart utility. Using Olympus RAW (ORF) and out-of-camera JPG, the resulting style provides amazingly similar color rendition. For most of the scenes anyway. I used both Olympus' "natural" and "vivid" JPG modes. Still for some scenes, I still prefer my initial, empirical, "color zones" style... In the end, it is good to have these style available and try them on different scenes.

It, including OpenCL for darktable, worked on 16.04. Perhaps conflicts can be resolved with 'apt-get -f install'?

For Ubuntu, amdgpu-pro is not much more, but a set of regular .deb packages. One can use the provided script amdgpu-pro-install, which installs all those debs. But they can also be intalled individually, using dpkg. With open source amdgpu already in the kernel, there is no need to install all the debs. That's why there is a --compute option, which merely installs a subset, i.e. a few packages with OpenCL libraries, in a standard, APT way. No compilation is necessary; it works with all the kernels, including the latest 4.12 RC. It never occurred to me that this is a hack, i.e. installing some libs, but perhaps there are reasons I don't know about. -- Šarūnas Burdulis math.dartmouth.edu/~sarunas signature.asc Description: OpenPGP digital signature

Or even better - could you process it yourself and post your xmp > file ? Here is my take: https://math.dartmouth.edu/owncloud/s/dt6IpL3RIHrYmSs The scene is back-lit, so most attempts to fill-in the shadows are likely to result in somewhat “unnatural” lighting. In such a situation the best probably would have been to use a fill-in flash, which might have also allowed to preserve details in the sky (reflection in the puddle reveals that there might have been some interesting sky). In my opinion, image is not underexposed — the sky part is overexposed. darktable 2.2.4; default base curve for the camera (no fusion). I assume we use calibrated and profiled displays, not only for darktable, but also whatever program is used for viewing the processed images is “color managed”. -- Šarūnas Burdulis math.dartmouth.edu/~sarunas signature.asc Description: OpenPGP digital signature
