Description

I tried to create a noise profile for my EOS 200D using darktable 2.4.1 and the gen-profile script from master.

It seems to work, but I do lack the necessary experience to judge if the plots look reasonable. I'm happy to take more pictures if necessary.

As I took 3 shots per ISO and the resulting coefficients seem quite similar, I've also created and attached a presets_mean.json file with the averaged values.

Thanks for adding the noise profile. :)

Just a quick question out of curiosity: What is the reason for adding 3 values per ISO instead of the mean?

The reason is that calculating the mean of parameters of a function is NOT the same as the mean of the function.
mean f(x,y,z) != f(mean x, mean y, mean z)
