I have been trying new film so I guess experminting with tie is what I need to do. Any suggestions to a starting point. And when do you really wnat to go N-1 or N-2 for that matter. Paper should print 6 zones so when do you wnat to go N-1? How many stops does the scene have to contain before you do this? I realize that it is artistic expression but just looking for starting points as I am gettign to learn a new way to develop my film.
