Hello, I've followed the very good procedure written to generate noise profiles and using a scene similar to the one I previously used for the Pentax K-110D, I made profiles for the Pentax K-1.

There was one thing to change however to preset.json: the maker/model entries did not correspond to what is in the exif (just a split of the model value?), I did that afterwards.

I'd like to submit the results for review and inclusion if deemed good enough: I have begin to validate a few settings using the benchmarking method, and others by human evaluation (given the number of ISO steps of this camera, it could take some time).

The profiles could not be uploaded here, so here's a link to retrieve them:

Thank you very much

Due to bad values, I started from scratch and with a more rigorous approach, but setting aside the intermediary iso settings.

The profiles:

And curves for parameters:

And benchmarks: (whole iso range) (100-12800 iso)
