RE: filmscanners: VueScan and white pixel clipping SS4000

Tony,

Thanks. These "whiskers" only show up on high-bit scans with VueScan but not
high-bit scans with Polaroid's software. You are correct that they disappear
on 8-bit conversion.

If not actual subject luminances, then usually you'd expect them to
indicate rounding errors during processing. They need not alarm you,
you'll find they vanish on conversion to 8bit.
