Re: [Digital BW] Re: Scan Resolution for a 4X5 Black and White Negatives

Hi Berel

While I agree with the first part of your post (don't exceed the
capabilities of your scanner), I don't believe that prints at 150 DPI (What
you get from a 4x5 scanned at 600 dpi, then printed to 16x20) will give you
"more than enough" resolution- more like just barely enough, if you are
lucky. Of course, YMMV.
