I don't have "Lock Exposure" so it seems the 9950F can't vary its exposure time.

Yes I can get the histogram for whichever frame I have selected,
haven't played with adjusting it much though.

Yes I saw those before. I'm a little reluctant to go this route but it
may be the only way to get great stuff right from the scanner,
especially for negs. That's the other thing to consider here, I'm used
to scanning slides. In Vuescan with my 2710 I'd just set the media
type to image and could use auto levels or white point and get an
excellent scan. With colour neg film you need to account for the
orange mask so I suspect that's where the film profiling really starts
to shine.

Tried neutral but then the colours go pretty bad. I adjusted my white
point so that auto colour gives me a white point at 100% instead of
clipping it at 95%.

This is true. But I think it's a little more individual for each frame
to get the best results. It'd be easy enough to play with though. I
could do my levels as an adjustment layer and then I can easily copy
that layer to other images and see how good it gets them. If I could
find a good set of settings for levels that might some time.
I should point out that I'm probably making a lot more out of this
than I should. I was just spoiled by being able to get excellent scans
of slides from my 2710 using Vuescan without the need to do much (or
any) post-scan adjustments (other than cleaning up dust and a bit of
sharpening). The scans I'm getting from the 9950F are really good,
they just need some work in PS. I get great shadow detail and nothing
is clipped.
