This interest me to, however it is not obvious, what you [re-]did to get

He just used images from a different Fuji camera.

This means DT will use a different matrix for the conversion.
And it seems that matrix, the one for the X-E2, doesn't have the issues 
OP is seeing with the one DT uses when fed with images from an X-T3.

Re: [darktable-dev] Import images from CLI

Hey Patrick

Thanks, these scripts are always useful. I have something different that
works for me here. I've scripted 1, 2, and 4. What I'm looking for is a way
to add photos to the darktable library from the cli, without opening
darktable

you might find useful my rename strategy:
  'lc;exiv2 -T ./*.{nef,jpg}'
  'exiv2 mv \-k \-r %y%m%d_%H%M%S_:basename: \.\/*.{nef,jpg}'
  
lc lowercases the filenames
change file-date to exif date-time taken
then renamed to YYMMDD_HHMMSS
  year/month/day/hour/minute/second
plus original filename  
  
190526_153344_dsc_5940.nef

[darktable-dev] Import images from CLI

2019-05-26 Thread Dane Goodwin
Hey all

Darktable is a phenomenal project, and I couldn't be happier once my photos
are loaded in the DB and I have some local copies for the road. However,
getting my photos to that point is quite cumbersome. I have a NAS where I
store all my photos, and the steps I follow to get my photos into darktable
are

1) copy the photos from my memory card to my laptop
2) sort them by date taken, and upload the folders to my NAS
3) open darktable and import the new folders
4) close darktable and use darktable-generate-cache to create some
thumbnails
5) open darktable and create local copies of the new photos that I want to
work on

Having a command to import images from a folder would let me automate this
completely, so I could plug my memory card into my laptop, run a single
command, let it run for however long it needs, and come back to photos that
are sorted, saved, and ready to go. A command named darktable-import with
an option to create local copies of the new images would be perfect for me.
I couldn't find anything that does this, and wanted to open the discussion
here. Is this something others might find useful?

Re: [darktable-dev] Naming Module Instances

2019-05-26 Thread Edgardo Hoszowski
I agree that there's not much space, so the description usually is not
fully displayed and the result text is confusing, but just hiding the
module's name won't probably do it, some other logic should be defined.

For instance, when creating a new instance the #{instance number} is set,
by just hiding the name we'll get #1 on all new instances.

Re: [darktable-dev] DT bad on skin tones?

2019-05-26 Thread Aurélien Pierre
darktable handles the matrices all the same way. It's simple linear
algebra, if it works for some matrices, it will work for all matrices.
But if the coefficients of the matrice are wrong, nothing magical will
happen.
