tribution of light and dark details can usually be
found which can be metered using spot
metering.
In this picture taken at the ballet, the metered
area was at the far right, partly outside the
picture area. If suitable areas are not availa-
ble, the dark details must be metered and a
correction made, resulting in a smaller aper-
ture or faster shutter speed. Stopping down by
half a stop (in extreme cases a whole stop) is
sufficient.
If there is considerable contrast between light
and dark parts of the image, the exposure
latitude of the films ceases to be sufficient to
register the full tonal range of the subject in
both the "light" and the "shade". The photo-
grapher must decide where he wishes to retain
the greatest detail. For example, a person can
appear as a black silhouette (under-exposed)
in front of a correctly exposed landscape, or
correctly exposed in front of a "burnt-out"
background (overexposed). A reading from
"light" and "shadow" and the resulting average
exposure usually leads to unsatisfactory
results because delicate differences in
brightness are lost in both the light and the
dark areas.
