Re: [darktable-user] Remove only one item from history stack

[William Ferguson]

Ideally you could create a style with the watermark module set to off, then
apply the style and get rid of the watermark.  But, there is a bug either
with the watermark module or the history stack and this doesn't work.  I
filed a bug report, but haven't had a chance to work on it yet.

In the meantime there is a workaround.  You can create a blank svg file,
add it to your watermarks directory, then create a style to apply it.
Then, when you want to remove the watermarks, you can select all the files
and apply the blank watermark.  I've attached my blank svg file and the
style I use to apply it.

Hope this helps,

Bill

Hallo Pascal,

Hello Bernhard,


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.


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.

thanks, I'll have a look into this.
Is this the right place for instructions?
https://www.darktable.org/2013/10/about-basecurves/





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?


No, better use the color checker module now.
https://pixls.us/articles/profiling-a-camera-with-darktable-chart/

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

Is this also to submit or only for personal use?
(I did not read the full article yet but I have a target from Wolf Faust 
which I used to profile film in the past).



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?


tools/extract_wb in dt repository.
Thanks, found this already and with some help of Rafa got this working - 
see other mail.

I'll share the results.




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?


As a GitHub PR here:
https://github.com/darktable-org/darktable/pulls

have to find out how to do this.

I created an empty

and ran the script again.
Terminal says:

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

Just setting the watermark to "off" should be enough to remove the watermark
from the image.
After that, compressing the history stack will get rid of the original entry
in the stack (along with any other superseeded entries).
