[filmscanners] RE: 8 bit versus 16

["Austin Franklin" <austin@darkroom.com>]

It really depends on if you are talking color or B&W.  For B&W, there is no
question, you need to use 16 bits for doing all but a minimum tonal curve
adjustment, but for color, for most applications you won't see any
difference using 8 bit data or 16 bit data.
