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
https://github.com/darktable-org/darktable/blob/master/tools/extract_wb
but I get
$ ./extract_wb 20190116_n5x0021.nef
/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in
`require': cannot load such file -- nokogiri (LoadError)
from /usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in
`require'
from ./extract_wb:53:in `<main>'
