Hi all.

This mail is primarily targeted to all the owners of Nikon cameras.

As you may have seen, an issue with white level for some
nikon cameras (or so i thought) was discovered by me:
https://www.mail-archive.com/darktable-dev@lists.darktable.org/msg01196.html

In the meantime i have adjusted white levels for all the cameras i
could find samples for.
But unfortunately, for some cameras i was unable to find samples.

Below, you will find a list of all the cameras for which i need samples.

IMPORTANT: if you see your camera in that list, it is imperative for
you to provide
a sample set, or else your camera will not be supported in next
darktable release!

NIKON COOLPIX P6000
NIKON COOLPIX P7000
NIKON COOLPIX P7100
NIKON CORPORATION COOLPIX A
NIKON CORPORATION NIKON 1 AW1
NIKON CORPORATION NIKON 1 J4

NIKON CORPORATION NIKON D70s
NIKON CORPORATION NIKON Df
NIKON E5400
NIKON E5700

NIKON E8800

(that is an auto-generated list, fresh version of the list can be
acquired by running
https://github.com/darktable-org/darktable/blob/master/tools/rawspeed-check-nikon-modes.rb)

Now, which samples do i need?

Each nikon camera has several settings:
1. Raw file bitness; can be 14bit and 12bit, not all cameras have that setting.
2. Raw file compression; can be compressed, losslessly compressed and
uncompressed. not all cameras have every option.

I need one sample per each combination.
I.e. for different cameras that can be from just one sample, up to 6
samples on the newest cameras.

Content of the sample does not matter, you could even put body cap on.

After taking samples, head to https://redmine.darktable.org/issues
check that the samples for that camera was not already provided,
open new issue
https://redmine.darktable.org/projects/darktable/issues/new
Tracker = "Camera support"
Subject = "${Camera maker} ${Camera model} raw support"

And attach samples.
If you can not attach samples (e.g. filesize), upload them somewhere,
and attach a link to samples.

(Also, it is a very good idea to also check whether rawsamples.ch has
sample for your camera, and send them samples too)

Roman.
