Description

I've profiled noise for the PowerShot G7 X Mark II following the instructions on https://www.darktable.org/2012/12/profiling-sensor-and-photon-noise/

Please, let me know if there's something missing or wrong. I followed the instructions as best as I could, and according to my testing and the output of the benchmark.sh script, the profiles seem to be working.

I'm attaching the tarball generated by gen-profile, plus the output of benchmark.sh
