Now Herb, notice I said "development" and not "exposure". The person who
asked about the spot-metering of an OM-4. At least half of the Zone
System depends on development. The difference in contrast you mention
is due to b&w film latitude. Of course, the same thing happens if you
have *any* spot-metered camera and adjust your exposure according to
careful examination of your scene.
