John,
What you have to understand is that all color negative technology is
designed to compensate for extreme contrast ranges; this could be from light
shadow or it could be filter induced. Think about why we shoot color
negative stock, the contrast range that can be handled is extreme to say the
least. The why is developer inhibitors, in the emulsion is a chemical
buffering set up that drastically slows development once a certain density
is reached. In color the flat contrast works as we see color but in B&W we
need white to black.
 The good news is that the information is there, you just need to burn and
dodge to your hearts content.
