Digital BW, The Print

I've been watching this thread for a while now and thought I'd share
something I found on Russell Brown's web site.  Although this thread
deals with scanning B&W negs 
and his method is more geared towards converting color images to
greyscale I thought it might be of interest to some here.  He uses
two Hue/Saturation adjustment 
layers on top of a full range color image.

He has a quicktime movie of it here  (7.5Megs)

He also has 820 kb pdf document here

I'm not sure if this would be of any use for an RGB scan of a B&W neg
but you never know.  It is very reminiscent of filtering for B&W
shoots.
