No PFI required. The settings are as described above and then exported to TIF. Then I simply do post-processing with G’MIC. (Sometimes, I do a bit more in raw developer but that is all I use PF for.) My computer is really slow. Took me a day(!) to do the testing.
Now, if I do exactly the same processing in G’MIC on all of the TIF, the results vary a lot. That is what I am concerned about. The Rec2020 linear no-clip + sRGB linear combination gives the cleanest result; i.e., if I didn’t make any mistakes while testing, which I believe I have in retrospect. In any case, I now know that certain combinations degrade the image.
Edit #2 Here is another comparison using [PlayRaw] Say! Synchronised-swimming Cygnets! What I did was cut negatives, brighten average to ~0.5, add contrast to get std to ~0.2, crop, brighten-contrast again.
