in
whole seconds. This scale is intended to tell
you
only how long the exposure release must'
be
de-
pressed.
The
green letter B stands for "Brief
Time."
When
you
set "B,"
or
any
of
the green
numbers
to
the index
mark,
the shutter opens when the expo-
sure release
is
pressed,
and
closes
when
it
is
re-
leased.':'
Here
is
an
example (see illustration): Suppose
f / 4
at
a
shutter
speed
of
1 second was a
correct
exposure. If, however,
you
want
to use f
/11
to
ob-
tain
adequate
depth
of
field,
turn
the
shutter
speed
ring until f
/11
is
opposite the index.
The
green
number
"8"
opposite the same index indicates
that
the exposure release be held down for 8 seconds.
There
is
no
number
2
in
the series
of
green num-
bers because its place
is
taken by the letter B. If, in
the above example,
you
wish to use f / 5.6, the expo-
sure would be 2 seconds.

5 screws
into

side
of
the exposure release. This makes
it
easier to open
and

the

without
moving the comero.
