Digital BW, The Print

Hi,

It appears you are scanning in raw mode, which means the scanner gives you
raw data, and you read that into Photoshop and set your setpoints and adjust
your tonal curves in PS, right?  You should (if your scanner driver allows
it) be able to do the exact same thing in the scanner driver, and get 8 bit
data out of it, as the scanner scans in high bit mode (which isn't 16 bits,
but something like 12) no matter what mode you select.  The difference is
where the setpoints and tonal curves are adjusted, in the driver, or in PS.

It's really got nothing to do with "16 bit scans", but whether you can do
setpoints and tonal curves in your scanner driver, and I can't imaging a
scanner driver that wouldn't allow for that.

Regards,

Austin
