Darktable K1 Mark II noise profile

GitHub - derekkite/k1mark2darktable

If you are using Darktable with the K1 Mark II here is a noise profile. Take a look and see if it works. There are multiple profiles for lower isos, I'm looking for something that doesn't over smooth.

EDIT: Oops, having trouble uploading it. Will update.

EDIT again. The presets.json is available

Can this file be installed in darktable? Or is better to wait for oficial support in a new DT release?

You can run darktable with these presets like this:

darktable --noiseprofiles path/to/presets.json

I would like to get some feedback on the presets. Some of the iso's have a few to select from, some more aggressive than others.

I had done that, but I get an error, I assumed I was doing something wrong...

It says:

$ darktable --noiseprofiles '/home/chema/Escritorio/presets.json'
[noiseprofile] error: parsing json from `/home/chema/Escritorio/presets.json' failed
/home/chema/Escritorio/presets.json:7:1: Error al analizar: unexpected character `<', expected value

How did you get the file? There are two ways. One is to clone the repository, the other is to select the presets.json on the web page, click the raw button, them right click save-as save the file.

I think it is merely a syntax mistake, Derek. Lose the single quotes around the file name and it should work.

There is no < in the json. I suspect the html was saved. You have to save the raw file to get valid json.

chm · 09-21-2018, 12:28 AM

Solved! you nailed it! it was the html that I was saving! Thanks!

But now there's another issue , I can't make it to work. If I open a raw file from another camera (k5) in the Noise reduction (profiled) module
it founds the ISO of the pic. But if I open a K1mkII dng raw file there's no option to select the ISO of the pic, only Poisson distribution, any ideas?

Can you copy and paste the command line that you are running?

I ran darktable --noiseprofiles '/home/chema/Escritorio/presets.json' to "import" the profile, it worked with the newly downloaded presets,json . At least it exited without errors

I run darktable from the menu (In linux mint) or from command line with a simple 'darktable' without further parameters and exists without errors

darktable --version output is

Attached a couple of screen captures, one from a K5 dng file showing profile for ISO 80 and the other (bigger one ) from a dng file from K1 mk II with no options available

darktable --noiseprofiles /home/derek/Pictures/2018/k1m2/presets.json

Try without the ticks.

chm · 09-21-2018, 10:58 PM

Already had tried with no ticks,
~ $ darktable --noiseprofiles /home/chema/Escritorio/presets.json
same result, no options in the profiled noise module

chm · 09-22-2018, 11:05 AM

Also tried reinstalling Darktable and deleting ~/.config/darktable, with no luck

I'm running a build from github. Let me try installing from debian to see if it works.

Later: It didn't work here with the debian darktable install. Let me find a workaround.

More: The maker field in v 2.4.x is different from v2.5.x I'll create a presets.json file for earlier versions.

Finally: It looks like you need to build from master or get the latest build from here https://software.opensuse.org/download.html?project=graphics:darktable:master&package=darktable

Then run with noiseprofiles

chm · 09-23-2018, 02:06 AM

Now it works!! That was it! Thank you very much!
Haven't tested a lot yet, but it works and does its magic with noise (although we all know it's difficult to find noise in K1mkII images ....

)
