		I just returned from a great week in Scottsdale with Fred  (and Dennis ), and I will use this forum as a way to ask other BTZS "alumni" ( who are much more experienced and knowledgeable )a few questions.
  By way of introduction, I am currently using the Canham 4x5 metal camera, and developing Tmax and Delta Professional using DDX 1:9, 75 degrees, using a Jobo CPP.
  To begin, has anyone found the DOF functions on the BTZS program to be of regular value in every-day LF photography?
  Thanks in advance for any guidance.   |
