Digital BW, The Print

Anthony,

Aside from the fact that this thread has degenerated into a "I'm right,
you're wrong." situation and all parties should give it and the list a rest,
you are essentially saying that 3 X 4 = 12 is not the same as 2 X 6 = 12 nor
the same as 4 X 3 = 12. While they are not the same, 12 = 12 = 12 or the end
result is the same regardless of how we got there. In the end the final
print is everything and the path chosen is immaterial. Don't worry about the
technical details at this level. Have some of your B&W negs scanned and make
some digital prints. Practice is much more important than theory.
