I recently has ocassion to view a cinematic masterpiece named "The Man Who
Was Not There", starring Billy Bob Thornton (how anyone with a name like
Billy-Bob, could get anywhere in life escapes me entirely).

This B&W visual stimulator was of such an outstanding image quality that I
am wondering how the effect was obtained.
For instance is it possible that the lighting cameraman used the Zone system
in order to produce the recorded effects?

There is at least one member of this group who actually works in the movie
industry, perhaps he migh care to waffle a bit and elucidate on the subject
generally.
