I am attempting to scan some 6x6 T-Max 100 toned negatives with VueScan. I
can't find any settingss that don't give me way overly bright and contrasty
images. The negs scan fine in SilverFast or PolaColor Insight but I would
rather use VueScan. I am using a SprintScan 120 with a glass carrier.

Try:

Input|Media type: B/W negative
Input|Bits per pixel: 48 bit RGB
Input|Lock film base color: ticked, r/g/b eached forced to 1.0
Crop|Buffer%: 0
Color|B/W Vendor: Kodak
Color|B/W brand: TMax400
Color|B/W type: D76 CI:.55<-still too contrasty, raise this number
Color|B/W curve: manual
Color|black point: 0.02%
Color|white point: 0.02%
Color|brightness: 0.7
File|Raw file type: Auto (48 bit rgb)
File|Tiff file type: 8 bit grey

Of course black/white point setting and the brightness
are arbitrary here as they depend on a specific image!

What version of VueScan are you using Mendel. Some of these settings don't
exist any more? e.g. 48 bit colour mode doesn't allow a black and white
points to be set. "B/W curve" is a function I've never seen in modern
version of VS. If you're locking base color it assumes you've already locked
RGB exposure. Why scan at 48 bits and convert to 8 tiff?
 
I am using VueScan 8.0.9.0

I just tried a scan of color neg film and gotr the same overly bright
contrasty results that I got with B&W. I've tried all the settings that I
could think of. Any ideas?

The negs scanned fine with SilverFast and the Polaroid program.

I tried deleting the ini file but no change.

Maybe my notes are a bit dated.

Did you read my notes carefully? The 48bit rgb I'm referring is set on
the input tab, 3 or 4 down from the top. I'm not at my home pc right
now, so hard to check.

Again, maybe my notes are dated. In them, the text to left of pipe
symbol indicates the Vuescan Tab this setting is on. I'm talking about
the field with: "none", "manual", "neutral", etcetera.

With actual color films, I follow advanced workflow instructions, IF I
use it. But with silver based Tri-X, I found just ticking "lock film
base" and setting the resultand 3 boxes each to 1 prevents shadows
blocking.

Why scan at 48 bits and convert to 8 tiff?

The first thing I'm saving is Vuescan Raw file, which I definitely
want to have as 48 bit, red/green/blue. I then do scan-from-disk from
these (after cleaning dust and scratches, rotating). I might even just
output jpeg. The Vuescan Raw Files is my keeper.
 
What we're the negs toned with? You could try adjusting the (RGB) Exposure
Control on the Input tab. I think if the negs are appearing "bright" not
enough light is hitting the neg. Check off the exposure lock and adjust it
from default of 1 to 2, then try 4, 8, 16 etc. see if that make a
difference. I'm not sure you can turn off the contrast correction and there
doesn't seem to be a "generic" B&W setting. Maybe someone could explain if
there's a difference on most scanner between using the B&W setting and
Colour setting. They all use the same CCD sensor so it's probably a mode
thing. I know when in B&W mode VueScan scans quicker 2.5 times quicker I
believe.
