EXPOSURE MODES
The camera offers two exposure modes: aperture priority mode or
manual setting. Choose one of the two options depending on
image subject, situation or individual preference.
Notes
• Image noise becomes apparent when using higher sensitivities,
particularly on uniform dark areas. In order to reduce this
annoying phenomenon, the camera will take a second “black
picture” (taken with the shutter closed) automatically after
pictures taken with slow shutter speeds and high ISO values. The
noise metered in this parallel picture is then digitally “subtract-
ed” from the data for the actual picture. In such cases the
message
Noise reduction Noise reduction
will appear with a relevant time value.
The doubling of the “exposure” time must be taken into account
for long exposure times. The camera must not be switched off
during that time.
• The remaining exposure time after shutter release is counted
down in seconds on the display for shutter speeds greater than
2 s.
SELECTING A MODE
▸ Set the shutter speed setting wheel
A
(Aperture priority) or
select the desired shutter speed (Manual setting =
M
)
APERTURE PRIORITY - A
Aperture priority mode sets the exposure automatically according
to the manually selected aperture. This mode is suitable for
pictures in which the depth of field is a critical compositional
element.
By selecting an appropriately low aperture value, you can reduce
the depth of field range, for example to make a face “stand out” in
sharp focus against an unimportant or distracting background.
Conversely, you can use a higher aperture value to increase the
depth of field range, so that everything from the foreground to the
background will be in full focus in a landscape shot.
