Exposure Compensation in the A mode: To make
an exposure compensation with the ASA/ ISO film
speed scale , determine the film speed that corre-
sponds to the desired exposure compensation va lue
by using the following chart.
For example, to make a
+
1 exposure compensation
when using ASA/ ISO 100 film, reset the ASA/ ISO film
speed scale to ASA/ ISO 50.

Exposure Compensation in the manual mode
(1/30sec. to 1/1000sec.):
To make an exposure
compensation, set either the lens aperture knob (in
the case of the LW-N ikkor, set its aperture ring) or the
shutter speed/mode selector dial so that at least two
non-adjacent LED indicators are lighted (one LED
indicates the shutter speed you select, one indicates
the shutter speed the camera 's microcomputer se -
44
lects). Another method is to move close to the subject
(or position it in the center of the viewfinder) and ob-
tain an exposure reading; then set the controls accord -
ingly and step back (or change the position of the
subject in- the viewfinder). When you release the
shutter, the result with be a properly exposed photo-
graph.
o
This technique can also be used to create intentional over-
and underexposures in normal lighting. The proper amount
of exposure compensation can be determined through trial
and error
o
Be sure
to
return the ASAIISO film speed dial
to
the
cor-
rect setting after you have finished your exposure
com-
pensation.
olt is difficult to use exposure compensation when shooting
underwater in harsh lighting conditions. An alternative is to
"bracket" your shots: take one shot at the indicated correct
exposure, and one each at the next largest and smallest
flstops (or next fastest and slowest shutter speeds).
o
Generally speaking, a
+
2 exposure compensation is re-
quired when shooting subjects against snowscapes and
similar situations, but that value will not always provide the
correct exposure. For best results, use an 18 % reflectance
gray card (available at most camera stores) for precise
exposure metering rather than using the ASAIISO film speed
dial. TTL exposure meters are calibrated to provide the
correct exposure when an 18% reflectance gray card is
used. If you do not have
a
gray card, hold the palm of one
hand at least
a
foot in front of the lens in the same light
as
your main subject and let the camera meter your hand for
the correct exposure.
