Digital BW, The Print

Lew,
I have the LS5000 but don't run it with Vuescan..  Just for kicks try this.. Scan the film using color rather then B&W and then convert it afterwards..B&W has a limited amount of density capture steps where color has infinitely more.. I think this might help.. worth a try anyway..

  Subject: [Digital BW] Grain/aliasing, CoolScan 5000 and VueScan


    
  I have an increasingly annoying problem in that what appears to be grain in
  my scans is worse at higher dpi's than it is in the quicky 500 dpi 8 bit
  scans I do as proofs. This is for traditional, 35mm, bw film coming out of
  my darkroom.

  >From what I've been able to read on the net, this may be due to aliasing &
  not the actual grain in the film (It's much worse than I'd see in a
  traditional, gs print.). Contrary to what I've read, however, it is not a
  matter of threshold iso/grain size issues, rather it's a continuum, getting
  progressively worse as iso/grain increases. It may not be readily noticeable
  at lower iso's, but close inspection reveals it to be there.

  Here are what I believe to be the pertinent the settings I use in Vuescan
  for my, hopefully, best scans:

  Media: B/W negative
  Bits/pixel 16 bit gray
  Resolution: 4000 dpi
  Number of samples: 8
  Fine mode: Yes (checked)
  Multi Exposure: Yes (checked)

  I've been playing, unsuccessfully, with checking/unchecking, no of samples
  etc... Medium size jpg's seem to produce better scans than the maxed out
  settings above, but of course, they won't work for larger prints going
  forward.
