OK, do (say) a multipass scan of (say) 8 passes, and save as a RAW 64bit RGBI TIF file. Import and preview with a setting (any setting) of your choosing. Now change the setting. Without any effort on your part, Vuescan applies the changes to the preview while in memory. You can do this an infinite number of times until it looks right - then scan from the RAW file to disk. Vuescan (as yet) does not have a Curves dialog box for local colour changes, and so it applies colour changes globally. Setting the Black/White points clips the tonal range where you want it. Changing the Brightness alters the mid-point gamma. It helps to 'play' with VueScan with the beginners/intermediate/advanced control settings, until you get a feel for it. There are quite a few canned film type profiles for Vuescan, and depending on how the film was exposed you will get a result - if not try a generic film type and tweak. Everyone finds VueScan baffling at first. Like a violin.
