Re: [Digital BW] 16-bit Scanning: Why?

2001-12-06 by sunshine_1451

I agree that it is essentially an aesthetic decision. However, if it 
is the case that the Kodak, Nikon, and Polaroid scanners in the 
4000dpi range are bit soft in their scanning output, then it would 
follow that most photographers would compensate for this by 
sharpening. I guess what I'm wondering is whether your experience 
with not having to sharpen scans is limited to format (medium or 
large) and scanner type. BTW I apologize for having forgotten to put 
my name at the end of the last post.
