3.0.1 looks and runs terrific, and built very easily under Debian Linux.
(if this isn’t the right place to post this, I’ll apologize in advance) I’m not sure if there’s a bug, or I’m doing something wrong - I’m trying to pick a different Nikon lens under “Lens Correction”, and the list of lenses doesn’t scroll - I can’t scroll to the lens I want to correct for. It’s listed in slr-nikon.xml (the LensFun database), but I can’t see it in the Darktable list because the list is so long.
Using the arrow keys I can get to lenses that I can’t see, but I can’t see the actual choice until after it’s been selected.
That doesn’t show the Gtk version. You could have it with: apt show libgtk-3-0 and check Version line. For example, on my system (Ubuntu), I have Version: 3.24.14-1ubuntu1
darktable use Gtk 3 but you could have some issues with Gtk older than 3.24.8 (or 3.24.7 can’t really remember which one).
Not sure on which Gtk version the scrolldown issue were fixed but maybe on 3.24.7 or 3.24.8. So if my memory is not too bad here, the best fix you could have would be the possibility to update Gtk to at least 3.24.8 version. Workaround you suggest is also a possibility but I suggest you to keep a copy of the original files before.
I’m sorry, Nilvus, I forgot to get back to you, trimming the slr-nikon.xml files worked for me, though I’ll definitely look at other solutions in the future.
I am now installing it to windows to check if it happens also there
btw, if it is not a huge task i can also do this, (Im currently studying for my masters in computer science and have 4 years experience in programming In C++, Python, C# and Java)
I just grepped through dt and RT sources, couldn’t find the camera. Rather new camera, just needs the data.
A bit dated, but this page outlines the sort of data required:
Particularly, color primaries are needed. An early source of these for new cameras is the Adobe DNG converter; I just looked through the DCPs from version 12.2 that I downloaded a few weeks ago, and I don’t see anything there for the A6100.
Having nothing better to do on a COVID-19 Friday morn (Colorado is shelter-in-place, now), I retrieved the Sony ILCE-6100 DPReview test raw, cropped the ColorChecker, and used the Argyll tools to make a profile. Here are the primaries from it, courtesy exiftool:
Red Matrix Column : 0.79448 0.27458 0.03847
Green Matrix Column : 0.22372 1.07974 -0.2321
Blue Matrix Column : -0.05449 -0.35432 1.02325
Used the camera metadata black subtract (512) and ‘as-shot’ white balance, saved as a 16-bit TIFF.
I then used the .icc as the camera profile to re-process the DPReview raw, looks nice. Can’t post it, however; not my image.
Ah, that seemed to work. If you download this and specify it as the input profile, you might be able to coax dt to open the image. Also, don’t forget the black subtract, 512…
