darktable 2.6

I totally agree. This is really a great release. Particularly the filmic and retouch modules mean a big step forward when it comes to processing my architecture shots :star_struck:
filmic because it allows such a great tone mapping and it became much more convenient to achieve the bright but still contrasty tones. (Nevertheless, it is great for so many pictures!)
And retouch allows to get rid of a lot of distracting stuff. And it is really astonishing how powerful it is. Not sure, if I could benefit from the frequency separation in architecture photography. But even without using this feature it gives great results.

Thank you very much for your outstanding work in the new release.

In the linked article “Filmic, darktable and the quest of the HDR tone mapping” there are some “Proper settings examples” for the filmic module. Is it possible to include them as module presets in darktable (I mean in the installation package)?

This would make the life of beginners easier since they can get ideas of how to use a module without learning the complex backgrounds of a module.

15

The development version, 2.7, has filmic presets and the saturation sliders have been reworked. So, if you can compile the git version of darktable then you can have them otherwise they probably wont be out until the next bug fix release (maybe).

16

Will version 2.6 added to the PPA for Ubuntu 16.04? In the OBS it is already present.

17

Yeah, I have added a ton of new presets in master:

  • B&W film emulations in channel mixer
  • Fuji film emulations in color checkr
  • Kodak film emulations in color balance
  • deblurring presets in equalizer
  • usual dynamic ranges in filmic
  • minimal modules selections for each purpose (portrait, landscape, architecture…) in the darkroom.

So, I hope it will give more examples on how to use the modules.

That’s a question for Pascal de Bruijn, I guess. Not sure he will support an old LTS.

I am able to build it on 16.04, so technically there seems no obstacle. I just did not manage to find Pascals email address yet to ask him. Could you please find his address and ask?

19

If you have a Launchpad accoundt, you can find his contacts in his Launchpad page:
https://launchpad.net/~pmjdebruijn

However, if you read what’s written in the ppa page…

Please do NOT contact me about providing updates for anything. I will update things when I see fit to do so. I do NOT do requests!

:sweat_smile:

K, sorry @aequalis, please ignore my stupid advice and do not contact Pascal. Isn’t there another source for ubuntu packages, with Opensuse or something similar? I have to research tonight … I would be happy to find a source as well, since I do not want to use my self compiled version for my production database, since I may have done something wrong.

21

With a clean/vanilla install of 16.04?

22

why not use the version from the OBS? it is built with the same files being used for the debian build.

23

Most probably not. But I am sure it’s all from PPAS, nothing installed manually.

24

That’s the OBS darix and I mentioned - so I guess, it’s time to switch from the PPA to the OBS. I was just wondering, why only the PPA for 16.04 didn’t received the update. :wink:

I just tested my self compiled version against the one from OBS, and I found that the self compiled one is by order of magnitudes faster. Any idea what’s wrong with the OBS build?

26

Probably nothing. Repositories use generic CPU optimizations for SSE2. Self-builds use optimizations for your specific architecture/processor.

If your CPU is recent and supports AVX/AVX2, it can give a serious boost to the performance.

But that could also come from the compilation environment (for example, missing dependencies disabling support of multi-threading or OpenCL, or different compiler).

27

No, it’s an old X240 from Lenovo. Both use multithreading.

What I also observed is that darktable seems to no longer use the embedded jpeg of unedited raws for preview, is this a recent change or am I wrong?

28

Check your preferences, there is an option to use embedded camera thumbnails or use the raws to process them internally.

29

The option is un-checked, meaning it should take the embedded jpeg. I’ll investigate further, but not today, it’s late already.

30

I must say this version 2.6 works perfectlty and I have noticed no bugs comparing to all versions used before. Really, devs, consider collecting donations, even if they provide you with just one more beer. Your work is worth being paid for either way!

Thanks! Nice to hear that especially since 2.6 has a good load of new features.

32

I second that. For the last two or three years (at least) darktable has had a bad tendency to crash when importing images. I reported this quite early, but no one seemed to have a solution so I just stuck with it. Now in 2.6 this has so far not happened even once: It’s been rock steady. That alone would have made me satisfied, and then all the new features on top of that, things couldn’t be better :slight_smile:
