Jeffrey,
lots of scanners scan in 16 bit, which helps, and Photoshop 6.0 lets you do
more functions while still in 16 bit, even sharpening, however I usually
don't sharpen files until I print, because I may print the same file at
different sizes....
Is the posterization you are referring to a result of the "orange" negative,
or are you talking about the conversion to 8 bit and subsequent actions
giving a "comb like" histogram that would give you posterization?

was to go beyond 8-bits of information and limit the use of software
manipulation that also posterizes (most things, especially sharpening).
This can be done by either going 16-bit or quad-tone (4 x 8-bit). >>
