I found some improvement recently on my D500 by playing with 
https://www.darktable.org/usermanual/en/modules.html#demosaic 
demosaicing before doing anything else.
I have adjusted the settings in such a way that the structure of the 
noise appears as "even" as possible. This makes the artifacts less 
conspicuous after denoising.

Worth a try I guess.

I took the profile Denoise_chinese

from https://dtstyle.net/

Some times I simply rely on it while others I only tweak the demosaic 
module to VNG4 two times full average or Amaze.


I should say however that I very rarely shoot at more than ISO 6400.

Never compared to RawTherapee... I had a bit of a rough start with it 
and then I just switched to DT.

Hey,

denoising in darktable is somewhat tricky:

Use the *denoise (profiled)*, set it to "wavelet" and set blend mode to 
"color". This eliminates the awful color noise. Use a *second instance* 
of denoise (profiled), set it to non-local means and choose blend mode 
"lightness". With that second instance i'll usually reduce the strength 
or opacity to my liking to keep some detail.


You can set some presets and have them apply the correct denoising 
automatically.

Well, that's probably not a good way to go. We had this issue in the 
"difference" mode in the past. This way you would get images with let's 
say L=0 and a=-50 ("highly blue saturated pitch black"). Due to the 
practical way how these "unbounded" Lab values are converted into 
monitor RGB you get some strange color artifacts, not the "black" that 
one would normally expect.




Or perhaps another option would be to just deprecate and remove "difference"
if we assume no one's using it.

Actually, you already have "difference" for that.

The main expected difference between "difference" and "subtract" is the way
to deal with negative values. "difference" takes the absolute value, while
"subtract" (in Gimp, but the one in dt is not really a subtraction for now)
just clips negative values to 0.

"difference" (in dt at least) just outputs a black image saying how
much the input and the output pixels are different (black = same, white =
very different).

Now, what "subtract" should do with colors is debatable, especially in Lab.
On the L channel, something like max(in - out, 0) would be rather natural.
On the a an b channels, I'm not sure what to do. Just doing in-out would
mean the final image would be black if the input and the output pixels
have the same colors (the same a and b). They'd keep the same colors if the

[OT] I usually do this with difference blend mode. For example when I want
to know in which areas affects equalizer I change temporary to difference
blend mode and can see it.

I have no idea ;-).

Actually, my guess is that "subtract" is useful to blend two totally
different images together (e.g. blend a black text onto an image
for a dodge effect). For darktable where blending is done between
the original image and the image transformed by the module, I'm not
even sure "subtract" is a relevant thing to do. The fact that it's been
broken for years without anyone noticing is probably a sign that no
one ever found it useful.



I am guilty of never using it in darktable, but the usage could be to 
see _where_ in the image the applied module is acting. I mean, for 
example, if you really are subtracting, and you are applying an high 
pass, you should see a black image (no variation) with just the edge 
highlighted.


Now, I have tried with a grayscale image and it seems to work, so I am a 
bit surprised... with a color image it is not working, I agree.

Re: [darktable-user] What does the "subtract" blend mode do?

I have no idea ;-).

Actually, my guess is that "subtract" is useful to blend two totally
different images together (e.g. blend a black text onto an image
for a dodge effect). For darktable where blending is done between
the original image and the image transformed by the module, I'm not
even sure "subtract" is a relevant thing to do. The fact that it's been
broken for years without anyone noticing is probably a sign that no
one ever found it useful.

Then, when you want to update

cd ~/.config/darktable/lua
git pull

Re: [darktable-user] Lua Export

[David Vincent-Jones]

Thank you Bill;
I was confused ... the documentation indicates that the 'official'
scripts are 'maintained by the darktable community', I had incorrectly
assumed that they would be updated as a part of the automatic process. I
now know better.
