EV
Exposure
Value
: A
number
representing
the
available
combinations
of
shutter
s
peed
s
and
apertures
that
give
the
same
exposure
effect
under
conditions
of
similar
sce
ne
brightne
ss
and
ISO
.
At
ISO
100
,
the
combination
of
a
one
-sec
ond
shutter
speed
and
an
aperture
of
f/1.4
is
defined
as
EV1
.
The
camera
can
be
used
only
within
the
EV
range
of
the
exposure
meter
.
For
example
,
with
the
N7S
/
N7SQO
,
the
exposure
metering
range
is
from
EV1
to
EV20
at
ISO
100
with
an
f/1.4
lens
.

Exposure
bracketing
Shooting
the
same
subject
a
number
of
times
at
a
range
of
different
exposures
to
attain
proper
exposure.
Three
shots
with
metered
EV,
under
EV
,
and
over
EV
exposure
are
performed
in
that
order
with
the
N7SIN7SQO
.
Automatic
exposure
bracketing
is
performed
with
varied
shutter
speeds
and/or
apertures.
Exposure
Compensation
In
a
situation
s
uch
as
when
your
subject
is
strongly
backlit
,
exposure
compensation
enables
you
to
intentionally
compensate
the
standard
exposure
value
measured
by
the
camera
to
create
a
desired
effect.
Exposure
compensation
of
-3
EV
to
+3
EV
in
1
/2
steps
is
available
with
the
N7SIN7SQO
.
Flash
shooting
distance
range
The
distance
range
over
which
a
flash
can
effectively
provide
light.
Flash
shooting
distance
range
is
controlled
by
the
amount
of
flash
output
available
.
Each
automatic
Speedlight's
flash
output
varies
from
maximum
duration
to
minimum
duration.
Close-up
subjects
will
require
lower
(to
minimum)
output,
while
more
distant
subjects
will
require
more
light
up
to
the
maximum
output.
The
flash
shooting
distance
range
varies
with
the
aperture
,
film
s
peed
,
etc
.
Flash
synchronization
~
Timing
of
the
flash
so
it
coincides
with
release
of
_lliI
the
camera's
shutter.
There
are
two
types
of
synchronization:
Front-Curtain
Sync,
which
fires
the
flash
at
the
start
of
the
exposure
,
and
Rear-Curtain
Sync
,
which
fires
the
flash
at
the
end
of
the
2
exposure.
Flash
sync
speed
Shutter
speed
at
which
the
entire
film
frame
is
exposed
when
the
flash
is
fired
in
flash
shooting.
The
N7S
/
N7SQO's
flash
sync
speed
is
1/90
sec.
or
slower.
