EXPOSURE
COMPENSATION-'---------------==---=------=-=
"Correct" exposure is a value based on combinations of
film
sensitivity, aperture and shutter settings necessary to
produce a
"tec
hnically correct" exposure result.
In
prac-
tical
photography, we often want to vary the exposure
results to create different versions of the same picture.
This
is
accomplished by using exposure compensation.
Exposure compensation can be accomplished
in
many
ways
. The accompanying chart indicates controls that
enable compensation with the Nikon S8-24 and the latest
Nikon
SLR
models.
In
addition
to
changing the exposure,
we
can also modify a scene's lighting by manipulating
the
light source, thus creating different lighting effects.

The
following is a brief explanation of the various
compensation methods, including those accomplished
automatically by the camera/flash computer control,
those accomplished through user-controlled operation
and
alternatives which manipulate the lighting
on
a scene.
As
the results can vary depending on individual condi-
tions, you may want to experiment with each method.
Experimenting for creativity is what this is all about.

Computer,
automatic:
Nikon mUlti-segment light meters
using advanced computer programs evaluate a scene's
brightness and contrast and calculate appropriate expo-
sure compensation to accommodate a wide variety of
complex lighting conditions.

manual
adjustment:
auto-
matic control as noted above, but with a user-determined
adjustment to the calculated exposure; accomplished
using the S8-24's
EV
compensation control.
Manual
adjustment:
turn off the camera/S8-24 auto-
matic controls and select any manual adjustment using
the S8-24's
EV
compensation control.

Sync:
not generally referred to
as a compensation method, but can be considered so
because it offers a "different" exposure result.
