2019-01-18 Thread Bernhard 

now it seems to work,
sorry for confusion.

I created an empty
/home/some_path/2019/src/external/rawspeed/data/cameras.xml
and ran the script again.
Terminal says:

$ ./extract_wb 20190116_n5x0021.nef
WARNING: Couldn't find model in cameras.xml ('NIKON CORPORATION', 
'NIKON D500')
  { "NIKON CORPORATION", "NIKON D500", Incandescent, 0, { 1.431640625, 
1, 2.411621094, 0 } },

You require nokogiri gem installed.
Execute:
  gem install nokogiri

It could fail because it needs some C libraries to get 
installed(sometimes you have it installed previously). In case of 
error you can find more infor here:

Hi,

according to
https://www.darktable.org/resources/camera-support/darktable
lacks of support for Nikon D500 and D850 (WB Presets and Custom
Matrix). When I start to work on this, I want to be sure to do
the right things.


https://www.darktable.org/2012/10/whats-involved-with-adding-support-for-new-cameras/
says in the first sentence:

“/Update: This post is a few years old by now, and while most
things are still valid there is at least one change: darktable
doesn’t use dcraw/libraw and more./”

The Color Matrix chapter refers to
https://encrypted.pcode.nl/blog/2010/06/28/darktable-camera-color-profiling/
for getting the enhanced color matrix. This is 9 years old =>
still valid?

The White Balance chapter points to a script
http://ufraw.cvs.sourceforge.net/viewvc/ufraw/ufraw/wb_extract.pl
that isn't available any more.
How do I get further?

So my questions:

  * Is the information given in the chapters “White balance
presets” and “Color Matrices” still valid or is there
another newer workflow documented somewhere (and if => where
to find it)?
  * Where do I submit the results? redmine?



In the meantime I found

Not necessary up to date. The D500 is missing WB presets yes, but the WB
presets are available for the D850.

And indeed the base-curves for D500 and D850 are missing.

No, better use the color checker module now.

You'll need a good chart (it8 if possible) to get good results.
