Mickey, the Zone System is/was a comprehensive system that began at setting the exposure, and ended with the print. This was the thrust of Ansel Adam's series '
The Camera', '
The Negative', and '
The Print.' Everything was a measure of setting what would be Zone V in metering, and exposing from that point. Then there would be N+ adjustments made during the negative development.
Zone V is nothing more than 'middle grey', and most light meters (external or in-camera) are weighted there. Fred Picker took this and suggested going one zone above, to adjust for limitations in the film, and in the silver print media. This helped beget the whole N+ development craze of the 80s and 90s. Somehow, adjusting the exposure +/- in a digital medium can mimic the effect, but risks blowing out highlights, or burying shadow detail.
In large-format film, it is brilliant. I used it to great effect in architectural documentation, with often less than stellar lighting conditions. Here is an example:

I was referencing the idea of adjusting the exposure to a Zone VI part of the image in post process--and then applying a number of contrast/detail enhancement filters or adjustments. My personal favorite comes from the Nik Collection, and is called "
Bleach Bypass." Wonderfully adjustable, it delivers this sort of image:

Play with the idea as you see fit!
I have loaded an article about zone system metering that may be of interest:
In some ways, large format is the easiest branch of photography to learn. After all, the camera only has a shutter button and an adjustable aperture ring. Simply compose, focus, and click...that's all there is to it! I'm only saying that...
