Description

I just created the noise profile. I believed this was difficult to do, but at closer look is a well documented process.

Btw, I got a:

$\033[31mERROR: Incorrect green channel.

and followed the instructions in #11539, a couple iterations and done. The results are very good

Let me know if I miss something

Thank you for profiling, but the results don't look good.
The images have to be much more out of focus.

Another attemp. Max aperture

In the example image: left side original image; middle with old parameters, right new ones. It smoot the picture too much, I think. Is this ok?

Also the new noise profile does not look good. It seems the sensor has a different noise model than it is expected here. I am sorry but I think I can't do anything here and can not include it. I let the ticket open now, maybe someone else has an idea how to fix it.
