One last thing. Just to make sure I get this....

Say for some reason I wanted to put the shadows on Zone 4. That would mean I shoot at 1/500th at f/5.6. Therefore if I take the shot at this exposure I will overexpose my highlights by 4 stops and would place the highlights on zone IX (too high) if I continue with normal development So I would then reduce development by N-1 to pull them back to Zone VIII ?
