There is certainly grain, look at the shadow of the blade on the chrome, but it
doesn't cause trouble.

I'm not so sure. How do the negs of 'friends' and 'self portrait' compare in
overall density? In my scans, grain is more
prominent in less exposed areas and/or areas with no detail. if the 'friends'
neg is thinner/lighter looking, it is
underexposed, relatively speaking, and the higher grain/noise may be a result
of that.
That would argue for positive exposure comp. on the indoor shots. Color Neg
film has lots of overexposure tolerance,
less on the under side. 'Self portrait' looks not to have any clipped
highlights other than the specular highlights on
the chrome. You would have to go down several stops to avoid that, and wouldn't
want to. I don't think you need any more
than at most 1/3 stop less exposure on that shot - it's probably perfectly
exposed if scanning were 16 bit and done right.
You might try some tests in room light like that in 'friends', exposing at +
1/2, +1, +1 1/2 and +2 stops. You may well
find that the auto scanning process compensates for the exposure and the noise
goes down.

As I recall, from some time ago, the trial version is also limited to 8 bit.
Even if the scans are 8 bit, you should be
doing editing in 16 bit, even if you go back to 8 at the end. Does the trial
version allow saving and using profiles?
It's really a help to be able to save film profiles, and NR settings for
different films and cameras/ISOs.
