VueScan technique help needed

[Bryan]

I have a negative I'm scanning that is a flash photo of people in
front of several lit-up halloween pumpkins. VueScan is
color-correcting for the orange background when I crop the whole
image. If I adjust the crop box to be just around the people in the
foreground, the exposure and color balance are beautiful. But no
matter what color setting I use (manual, neutral, none, white balance,
auto levels, etc), when I crop the whole image and redisplay, the
color balance goes way cyan to compensate for the orange background.

Is there a technique I'm missing on how to make this work? How do I
lock in the automatic color balance and exposure for the people in the
foreground, then crop the whole image and scan?

Thanks!
Bryan

One way of approaching it:
Preview, Input|Lock exposure, Preview, Crop till you get an acceptable color
balance, Input|Lock image color, Recrop and Scan.
