Vuescan settings for FS2710

I'm having trouble getting accurate colours with any of the settings
in VueScan with my CanoScan FS2710. Using the included CanoCraft
software, the scans come out looking fine immediately.

I have Vuescan set to no colour balance (although any of those
settings looks poor) and I've also tried most of the negative
brand/vendor/type combinations close to what I'm using (mostly kodak
gold 400-8 right now, which isn't in the list).

Any suggestions would be appreciated, right now I'm stuck with the
canocraft.

I have been using Vuescan on Linux for a whopping two days, now, and have
done about 100 slide and negative scans with it. I set "media type" to
"35mm film", "scan mode" to "color negative", "color balance" at either
"none" or "auto levels". The results have been very good so far. Of course,
I almost always feel a need to tweak the image in The GIMP before I am
finished with it, but Vuescan does a pretty good job. I had been using
Canoscan (the stuff that came with the scanner) on Win98, and I think I
like Vuescan better.

Oddly enough, I had been having the problem you describe while using XSANE,
which would show the prevues in pretty good color, but would not save the
scanned image that way -- so I switched to Vuescan.

Now if I could just figure out what to do about all the graininess on my
negatives...

I've been getting half-decent results (not even sure of the color neg
film brand, scanned it for my daughter), with the following settings.
Of course, it's largely dependent on the film and processing, but you
might want to try this. Autolevels seems to be the only color balance
setting even close!

----

Color|Color balance: Auto levels
Color|White point: .02
Color|Black point: .02
Color|Brightness: 1
Color|Brightness red: 1
Color|Brightness green: 1
Color|Brightness blue: 1.1 (to eliminate green cast, ymmv)
Color|Negative Vendor/Brand/Type: Generic/Color/Negative

----

The result isn't bad, but (still) has a bit of green cast, to my eye.
I think it used to come out better, with earlier releases.

----

I get superior, spot-on (I think) color, plus more punch, by opening
the Vuescan raw file directly, in Photoshop, applying and converting
to a profile that was supplied with my scanner, then doing a minor
gamma adjustment (a bit darker), and .01/.01 wp/bp clip.

The latest versions of Vuescan have black and white point setting
graphically. Set the points on the preview scan (top graph), and see the
results on the proposed curves in the bottom graph. Available in manual
mode, of course. I've gotten so I rarely tweak the image in The Gimp,
except for the odd cleanup.

Open your image. Left click on the image to get the menu. Click on
Filters, then on Enhance, and on Despeckle. Try the default parameters.

Strangely, I find autolevels can often produce pretty strange results.
White balance is usually better. But the most useful thing if colour
is difficult is to try right clicking in a neutral grey area and using
the manual setting. This is quite wonderful, I find. I have a lot of
Kodak Gold film and Gold 100 Gen 2 works well for me, seeming to be
very different from all the other Gold ones.

Color "None" can be useful but it will (intentionally) produce a very
flat result.

Also, film base colour settings can have a significant effect. Since
none of the colour settings affect a raw file output with scan, you
can use a raw file and then experiment with all the settings by
scanning from the raw file. Setting film base colour by scanning in an
"easy" raw file and then locking film base colour before doing the
"difficult" one has also helped.
