Digital BW, The Print

Thanks Clayton,

You answered my questions thoroughly and I have a better understanding
of what I am doing.  Your interpretations of what I was asking were
right on, despite my misuse of the terminology.  I will take your
advise and do more experimental prints to determine what is best for me.
