1. Hi!

Thanks for the release!
I’m pretty sure i found some bugs: When importing photos it looks like $(EXIF_YEAR)$(EXIF_MONTH) $(EXIF_DAY) is now being resolved to the import date instead of the day the photo was taken, so$(EXIF_DAY) and $(DAY) now resolves to the same date. Looking at the EXIF info in “image information” in Darktable, the date seems to be correct. Also, the ~ sign no longer translates to the home directory as i believe it did before, but rather creates a “~” directory in the home folder.$(HOME) works properly though.

Hope this helps.

2. Only thing I really miss in darktable: synchronized zoom when viewing multiple pictures. This is basic for culling / selecting the best focused shot, when shooting sports or bracketing. Not sure about other photographers but for me culling is the first step after shooting and this is a showstopper vs. ASP. There is a feature request for this that is 4-5years old now, and a long list of ppl following it :/

• as of synchronised zoom: you can go to darkroom mode, zoom/pan to where you like, and use space/backspace to go forward/back in the list (use colour labels to only list the images you’re after before this in case they aren’t next to each other anyways).

also it’s possible to use snapshots between images to facilitate closeup comparisons.

but anyways, if you like the workflow better in ASP and are already familiar with how things work there, you should absolutely stick with that software, no need to learn everything from scratch in darktable.

3. Nice to see the project move forward! Kudos for the quality work done!
Long term darktable follower but not yet a convert here – patiently waiting for synchronized zoom to be supported. As a photographer, the first step in my workflow is culling/selection of photos worth processing; I tend to take multiple shots rather often and synchronized zoom to review & compare focus and exposure is fundamental; that’s the only one feature from ASP that I can’t go without. There is a feature request for darktable opened many years ago and every so often this is re-requested, hoping that at some point it will get some dev attention – at that point I will become a convert :)

5. Dear DarkTable 2.0.0,

Gorgeous App. Font size and controls unreadable,
Every character is tiny. Very hard to work with in this
regard. Little information, if at all, addresses this
illegibility. Wish I was able to solve this.

Thank you
for creating such a beautiful work in progress.

• Please file a bug report [0] and attach a screenshot. For the time being, in case that is a high DPI screen you are using there, you could try to set screen_dpi_overwrite and screen_ppd_overwrite in ~/.config/darktable/darktablerc to something that makes sense. The default of “-1” means autodetection but that might fail in some cases.

6. Thanks for a brilliant release, love the gamma check!
Just a note that in darkroom if I right click on over/under exposure, softproofing or gamut check and try to change one of the settings the list of available options appears underneath the settings menu.

7. Just upgraded to v2.1. Have not tried it yet. But it does work on my brand new 4k monitor. Just great, thanks.

• Do you compile darktable yourself or are you using packages? I am asking, because there is no 2.1 release. That “version” just denotes our current unstable development cycle. It’s fine to use that if you know that it might break without prior notice, just don’t expect it to be a stable release.

8. Just updated to 2.0. I will spend some time checking the new features and other changes. Thank you for your effort and great work! Happy 2016 from Spain and thanks for this huge Christmas present ;)

9. I just upgraded and played around with it for a while. The most significant improvement for me now is that it doesn’t crash anymore when clicking on a thumbnail to go to darkroom mode when the thumbnails are still loading. Even though this only happened occasionally, its absence is really nice. And, it looks as great as ever. Thank you.

• That happened to me all the time with 1.6.8. It was really getting annoying. The speedup in the loading times for the thumbnails is pretty nice though.

10. Thanks a lot for this new release !

I just installed on xubuntu thanks to Pascal de Bruijn ppa. It works like a charm.
One question though, regarding the lensfun usage.

The ppa does not provide lensfun package anymore, but the lens correction plugin seems to work without it, and darktable already have a lensfun database installed (I don’t think I had lensfun installed previously).

I tried to update lensfun and lensfun database by installing the 3.2 version from lensfun website. I installed lensfun 3.2 with Cmake, and I replaced the lensfun .xml in /usr/share/lensfun with the updated ones. The new lensfun database format version 1 [0] seems to be not usable by darktable.

Replacing the lensfun xml header from to allows Darktable to read the database, and I can applied correction for a SLR (nikon D2X) + lens (nikkor 18-200mm vr I).

This workaround does not work for my compact Sony RX100 mII. The camera is recognized, but the lens is not.

Looking at the xml syntax in compact-sony.xml shows some evolution between database version 0 and 1.

Is there any other solution at that time than manually modifying the xml files to fit the syntax to the database version 0 of lensfun (darktable 2.0 compilation with lensfun 3.2) ?

Last question, I have a noise profile for D2X ready to ship, where do I need to send it ?

Happy new year 2016 !

• I’ll try to answer as many questions as I can. :)
Regarding lens recognition: Check if the lens is correctly identified by exiv2, if not fill a bug there[0]. Also check if it is already in the latest lensfun version, if not you can take calibration pictures to add it, see the instructions by a member of the community for both aspects[1].
Regarding lensfun update: Better ask at IRC or the mailing list, both mentioned at the contact page[2].
Regarding the noise profile, open a bug report at darktable redmine[3].

HTH Simon

• Thank you for the detailled answer,

the sony rx100 ii is recognized, and is included in at least last lensfun update, so i will give a try on the mailing list !

I will open a bug report for D2X noiseprofile

Many thanks !

11. Hi,

I just upgraded on Mac OS and all my old images are now way too small in the viewer and on export (image looks like a tiny stamp on a large black canvas).
I checked everything and found that my lens-correction causes the problem. When I open one of my old images (processed in 1.6 before upgrading) the lens-correction in the history stack is now set to “scale 0.100” instead of “scale 100”.

Is there any way to change only this module in the history stacks of all my images?

Thanks a lot,

Malte

• …in case someone runs into the same problem (and is also new to Darktable), I managed to fix the problem after studying the manual:
I corrected the value in “lens correction” for one image, copied only that in “history stacks” (lighttable) and then “append” to all other images.
The result is the correct lens correction and all individual history stacks still intact.

Another problem I’m having is that the font size is good on my macbook, is much too small though when I attach an external monitor using HDMI. manually adjusted the dpi for now but the auto detect seems to only consider the macbook display and not the external screen.

Thanks!

Malte

13. Hello Guys,

this is a wonderful thing! Unbelievable, there are people paying lots of money for software instead of paying you attention.
I am a hobby photographer with not enough time to learn how make all your modules work for me but all my needs are more then fullfilled.
My english isn’t that good, that the manual could help me very much. Perhaps somebody knows where i could be teached in Germany (Volkshochschule etc?)
I would like to pay some attention by paying donation for your work. Where do I get Information?

14. I accidentally updated version 1.6.9 to 2.0.0 on Linux Mint 32 -bit cumputer .
Jpeg operation is perfect but with NEF files crascht the program.
Downgrading back to 1.6.9 is no longer possible .
Maybe someone knows a solution how I can install version 1.6.9 yet again ?

15. Unfortunately, I did the upgrade to 2.0.0 on my 32 bit machine .
Jpeg work well but with NEF files crascht darktable .
A downgrade to 1.6.9 is not possible …. so bye bye darktable .

16. Darktable 2.0 just hit Debian Testing “stretch”

Looks/feels great! Thanks for the effort!

17. Just wanted to say I love the new “trash” feature. It’s made a real difference to my workflow for such a simple change.

18. I am facing the same unhappy decision as many a Mac-based photographer: what to do when my creaky old copy of Aperture can no longer be supported. I would like to migrate from Aperture to Darktable most likely, as I’m not pro enough to pay the high fees for LR or other alternatives. Besides, I believe strongly in open-source software (and have built a lot of it on my Mac!). I use GIMP, not Photoshop :-) and I’d be delighted if Darktable can meet my modest needs.

However, I have invested a lot of time in keyword-tagging my images, creating albums for specific purposes etc.

Does anyone have a strategy guide for migrating from Aperture to Darktable without losing all of that effort in classifying, grouping, rating and tagging photos? I have over 40,000 images and just can’t bear to start over from scratch with the cataloguing. Would “write IPTC meta-data to masters” help?

• While writing IPTC to the images would probably bring the data over to darktable I am strongly discouraging that. Changing raw files is never ever a good idea. We had quite a few people who lost their images due to that, and sometimes the problems only show up in the long run.
Does Aperture allow writing XMP files? Or some other sidecar format maybe? If you need help you should probably come to IRC or the mailing list (see the contact page for details).

19. Is anyone running darktable 2.0 on an iMac 4k (retina)? How does it perform? Does it have OpenCL support (preferences > core options)? Any other observations? I am considering buying the 21.5 inch version, and any relevant comments would be helpful.

• Replying to myself in case someone lands here with the same question. I installed darktable 2.0 on a friend’s 27-inch iMac 5k (retina) and it runs just fine, though the text labels are a bit too small. One setback: OpenCL support seems to be missing, that is: the check box in Core Options is unclickable.

20. Thanks houz for the advice. For the moment I have decided to upgrade my old unused Lr v4 to v6 which will (mostly) run fine on El Capitan. That cost me about \$100, which I think is worth it in terms of time saved in the short term. However, Lr 6 will soon be ruthlessly obsoleted I am sure, and so I’ll be installing and playing with darktable in parallel, so that I have a real community supported open source solution for the longer term.

BTW, Apple has egg all over face the last couple of years imho — migration (forced by Apple) from Aperture to Photos seems to be impossible for many users with large photo libraries (myself included). I have spent a couple of days now trying it, total failure; results from others who have taken the issue up through levels of Apple Support are very discouraging. What a PR fiasco. Looks like Apple has made a strategy call to go for the consumer market and abandon the media professionals (at least the photographers).

So… I am very, very glad that the darktable project is rolling and hope I can contribute something useful along the way. We do need an open source tool of the same stature as GIMP, for photography cataloguing, rating, organising and editing.

21. Hello. I try to install Darktable 2.0 on linux mint, but i’m unable to do it . How can i do it? thanks.
