CENTER-WEIGHTED FILL-FLASH
While the Matrix meter can automatically measure up to five
different segments of the scene's brightness, the Center-
Weighted meter measures the entire scene and emphasizes its
reading on the center area. By pointing the center-weighted area
at different parts of the picture, you can choose which bright
ness ievei you want for the basic avaiiabie-light exposure, as
compared to the Matrix system which uses computer evaiuation
to determine the brightness/contrast ieveis upon which exposure
wiii be based.
if the brightness vaiue you have seiected is within the controlied
shutter/aperture range possibie, the fiash output compensation
wiii be automaticaily set for a naturai fiii-fiash effect. The amount
of computer seiected automatic compensation avaiiabie varies
with each Nikon SLR modei. For defaiis, check your camera
instruction manual, if you select a brightness value beyond the
controlled shutter/aperture range, the fiash output will be set
without compensation, as with standard TTL flash operation.
