Stan-

Shooting architecture I routinely handle scene brightness ranges that
approach and sometimes exceed 14 stops (see:
http://www.jobousa.com/jq/jq9903.htm#UPBK). There are two article listed
there, "The Jobo/Digital Darkroom Workflow" describes one approach to
handling high contrast scenes/subjects; then scroll down the page to "Taming
High Contrast in Black & White Photography".

There are no "normal" or "common" brightness ranges. There is only a relative
degree of predictability that over time emerges from a photographer's
experience. However, on a "normal" or "average" clear day our perception of
the world will easily include scenes that exceed a given film's ability to
record texture and detail.

By the way, spot meters are notorious for flare and most are not color
accurate. Older meters may also have "memory fatigue". Any or all of these
limitations can easily mask the true contrast range of a scene or subject.
