TTL EXPOSURE METER-Continued Extreme-high

situations
If
the
black needle remains in
"A"
or
"B"
after
all
possible
aperture
settings have been tried,
then
the
available light
is
too
bright
or
too
dim
to
cover
the
meter's
EV range. Switch
to
a new film
that
matches
the
available light
or
mount
a neutral
density
(NO) filter
onto
the
lens
to
cut
down
on
the
amount
of
light
or
use artificial light
to
increase luminosity, whichever
is
appropriate.
