Digital BW, The Print

Joseph:  Regarding posterization...I believe the advice you are 
getting regarding scanning at 4000 dpi at the input size is right.  
Do your major tonal adjustments in 16-bit only.  When upsizing to 
11x14, do so in small increments (maybe 2-3 inches at a time.) It 
only takes a minute to upsize in 5-6 increments using this method).  
Finally, go easy on your sharpening.  Hope this helps...Val
