Digital BW, The Print

Hi Truman,

To be honest, I have done all of my B&W film calibration work via a wet darkroom and a borrowed densitometer. I have gone on the assumption that a good printable negative will also scan well. As long as I do my part and develop absolutely consistently then the negatives are generally predictable (not always good images and worth printing, however). I usually place the highlight I can't do without on Zone VIII (with a spot meter) and let the other stuff fall where it may. Anything beyond zone VIII is usually a specular highlight of some sort with no useful information to be had from it.

  I've always done this. I've been experimenting a bit lately. If a 
  scanner is in the loop and it is a 16 bit scanner, I have been making 
  sure zone 3 has good detail and have been developing a "bit soft" to 
  make sure I have good highlights. By using 16 bits in the scaning 
  process you have sufficient dynamic range to expand the highlights once 
  in the computer. This seems to give very nice highlight detail and 
  minimizies the chance of blowing out a the highlights in the development 
  process.

  Any thoughts or feedback?
