Thanks for the additional advice, the tips, and also for the dissuasive
warnings which on a scientific point of vue are certainly founded!
To Don Hutcheson: I just got hold of your PDF and will study it
carefully. Your resources have always been a great help. Will try your
actions as well. Thanks!
Seems that this part sent already twice got filtered out for some
unknown reason, so here it is again:

Some additional remarks after more trials:
I have downloaded a trial version of ColorNeg as suggested by Tyler. The
program works and is worth a trial. But do the colors always please,
there I am not fully convinced. Some tones look artificial and the flesh
tones are sometimes sandy. That's for my experience with my negs and the
NEF files from the Nikon inverted with ACR. Your mileage may vary. But
thanks for suggesting!
Finally, I think I will settle for the following method: Once the image
has been opened in 16 bit mode with ACR using a linear curve and no
sharpening, I prefer to simply invert the image in Photoshop, crop, add
a level adjustment layer, press Auto and fine tune the RGB channels for
color balance and contrast. Sometimes, leaving some of the film border
can help by picking its color to neutralize the mask. Though not
perfect, the images developed that way have natural colors with no such
a big job on them. An alternate way is to neutralize the mask in ACR
with the neutral tone color picker. Then the scratches removal can be
done in a row and the image saved fully edited. Or it can be further
enhanced in LightRoom later. All right, some say ney to that method but
just remember that it is intended for family photo archives, not for
printing full page in magazines!

Paul, just in case you don't know it, the image processing
algorithms in LR and ACR are identical.
Yes I knew it and was puzzled. Further trials have shown the culprit: I
had a medium contrast curve set by default in ACR instead of linear,
which produced unwanted unaesthetic shadows on faces. Now, comparing
apples to apples, it's on par. Thanks for your remark!
If the tip you found for making conversions from negative to
positive using ACR curves is from Martin Evening, that works for B&W,
but not for color. I've tried it in both RGB and Lab and it failed.
Yep that was the one. Leaving some of the film border allows using the
neutral color tool to neutralize the film mask. But then the rest is
like playing trumpet in a violin! You can get what you want but at the
expense of more fiddling than reasonable. Saving presets is the only way
out. I think that the easier way out is the Photoshop process exposed above.
Thanks to all for having shared your experiences,
Paul
