Exposure measurement in special cases
The exposure
meter
of the Nikon FM2 adopts the center-
weighted exposure measurement system in which approxi-
mately 60
% of the total amount of light is measured by the
12
mm
ยทdiameter circle at the center of the focusing screen.
When the background of the main subject is too bright and the
main subject is not centered within the frame, the result is
underexposure (see Fig.
1)
. When the background is too dark
and the main subject is too bright with the same framing as
above, the result is overexposure.
To
compensate-
1)
Focus on the main subject with the composition you have
in
mind.
2) Move the camera to center the main subject in the viewfinder
(see Fig. 2) and perform exposure measurement.
3) Move the camera back to the position described
in
1) with the
exposure setting described in 2) and depress the shutter
release button.
This way, you will be able to obtain
correct
exposure.
