[filmscanners] Re: 8 bit versus 16

["Bob Frost" <bob@frost.name>]

Austin,

I've tended to use the 16bit (14?) output from my Nikon 4000 scanner and
stay in 16bit (because the maths argument sounds OK, and Bruce Fraser seems
to be in favour of 16bit). However, I'm just trying out a Minolta 5400, and
the 16bit files are 233 MB! I might just accept your argument and reduce the
size of my files back to about 100MB by converting to 8bit.

Exactly, but to claim that you "need" to use 16 bit data (for color) is
simply wrong, and was my point, and why I was very careful in what I said.
People can tout this, and espouse theory, all they want, but reality shows
otherwise.  If you want to argue this, it's important to understand what the
impact of theory has on reality.  As I've stated clearly, 16 bit data *MAY*
be beneficial for *SOME* images, but not for all.  For some people, it may
be more significant than others, depending on what it is they photograph.
