Camera Support #10868
Canon 760D noise profile
I recently acquired a Canon 760D camera and would like to know what exactly is needed in order to support it. According to this page: http://www.darktable.org/resources/camera-support/, it currently lacks WB preset, noise profile and colour matrix. I think that last one is going to be fixed by http://redmine.darktable.org/issues/10613, but the other two remains, especially noise profile that currently makes darktable unusable for me. :(
There might be other things too, but the following page (referred from previous one) looks (quite normally after all) outdated:
Especially, I think that with 2.0 you removed libraw or something like that. So, my question is which steps should I follow exactly to bring all what is needed to support my camera in darktable and projects that darktable depends on (like capture this kind of pictures with those kinds of settings and provide us with them or run this script here). :) Also, it probably worth it to add a (wiki) page about this, or just directly to the aforementioned page. And if other projects are involved, links to similar pages for them. ;)

- File dt-noiseprofile-20160316.tar.gz added
- Status changed from New to Patch attached
- Target version set to Candidate for next minor release
While waiting for more input from your side, I took the time to do some noise profiling. So here you go.
I’ve kept the original pictures if you need them too.

- Affected Version changed from 2.0.0 to git development version
Hey, redoing the profiling with the original images results in something decent but not ideal. We could probably get a better profile if you included more tones in between full white and full black. See these examples:

The submitted noise profile differ a lot. As there was an error in creating the noise profile in older darktable versions i think the profile should be calculated again with a recent version. Afterward it can be added (and wouldn't take as long as the old profile :-) ).

Here you go!
By taking a look at the PDFs, it looks way different indeed, especially for ISOs of 200, 400, 3200, 6400 and 12800. Tell me if that’s good for you, else I’ll do new shots when getting back home in ten days.

Sorry for the huge delay, I’ve made some unsuccessful attempts and then had to do a lot of other things.
I’ve made another hundred of attempts during the past week, to no avail. Curves look always completely wrong. Running the code against the previous series of pictures give the correct results, but it seems that I’m unable to choose a correct view/lighting… I’ll try again later but for now I have to let this aside again.
