Rollei 35 - Pre-Selecting Apertures 7; C O R R E C T E X P O S U R

For
distant
vicws with near forcgrounds
set thc
infinity
marking
co
to the depth of
field mark
for
the aperture
in use. That extends
the c{epth
of f ield to the
ncarcst
possible point in the
forcground.
@
Pre-selecting
Apertures
According to the type
of
subject
you
can line
up the matching
pointer
with the meter needle
by turning
either thc aperture
wheel
or the
shutter speed wheel.
With moving
subjects
pre-select the exposure
time
to make
sure of a
suitably
fast shutter
speed. Then
match up the
pointers by turn-
ing
the aperture
wheel.
If
on the other
hand depth of
field is more
important,
determine the required
aperture and
pre-seicct this.
Now
m:rtch
up the
pointers
by
turning
the shutter speed whcel.
If necessary
complete
the exact matching with
the aperture
wheel. Selected speed
have
to be in click-stop
position.
In every casc
the camera must point at the
subject
while
you
line up the
pointers.
@
Correct
Exposure
As a basic rule,
always
point
the camcra
whilc
taking exposure
readings
(1)
exactly in
the
direction of
the subject
(2). Inadvertent
tilting
of
the camera
-
for example
into the sky
while
taking landscape
views
falsify the
reading
and in this case lead
to under-exposure.

The
exposure
meter evaluates
the average
brightness
of
the measured
subjecc
field.
With
subjects
of average contrast
it automatically
indicates
the correct
exposure.
But even
with
shots
of considerable
brightness
range
you can
take
the readings
in such a
way as to
ensure
correct
exposure
for the main subject.
Normal
subjects:
the view is lit
from the front
or at an
angle from
the side. There are no
heavy shadows, and
dark and bright areas
are
balanced.
(This uniform
front
lighting also
yields
the most
saturated colours in colour shots.)
Result: The
measured exposure
is
correct
for
the
whole field of view.
A special case: The
main subject
contrasts strongly
in brightness
against
the badrground. For example,
with a
portrait of a suntanned face
againsr
bright clouds
an
average reading
would give
too
mucfi importance
to the sky. Yet it is
the
head whicl
matters for the exposure.
The
right way: Take a close-up
reading
with
the camera
near the subject
(3)
until the
main
object completely
fills the finder. After setting
the exposure
go back for shooting to the
pre-
vious viewpoint
(4).
