  BTZS principles don't apply to digital imagery closely enough to be reliable and I'd advise against trying to make them work. In other words, digital is a brand new ball game with different rules and different players.
  There are quite a few books and articles that deal with digital calibration methods. I can recommend Mark I. Nelson's new book, "Precision Digital Negatives" as one authoritative source of information.   |
