EXPOSURE
Automatic Exposure Mode
Exposure refers to the amount of light which
strikes the film, and is controlled by a
combination of aperture size and shutter
speed. The correct amount of light, called
correct exposure, depends on the film speed
(indicated on the film package, e.g. IS0100
or.lSO-200).
The automatic exposure function
automatically sets the correct exposure. This
camera employs two types of automatic
exposure modes: programmed auto-
exposure and aperture-preferred auto-
exposure.
With programmed auto exposure, the
camera automatically selects the most
suitable combination of F stop and shutter
speed for the existing lighting conditions.
This lets you concentrate on composing your
shot and releasing the shutter at just the right
time.
With aperture-preferred auto, you select the
desired F stop, and the camera automatically
selects the correct shutter speed. Aperture-
preferred auto gives more artistic freedom of
expression and creativity by selecting a
desired F stop to control the blur of the
background.
Program Chart (FULL AUTO)
The following program chart is for 28mm
wide-angle and 110mm telephoto focal
lengths. According to the focal length, the
camera's program itself changes. When the
subject is brightly lit, the F stop and shutter
speed change simultaneously. When the
lighting is darker, the aperture remains wide-
open and only the shutter speed changes to
as slow as 2 sec. to match the available light
(ISO 100).
In the standard shooting mode (refer to
p.40), if the built-in flash has been flipped up,
it will automatically fire in dark lighting or
backlit conditions. The shutter speed will
be
fixed at 1/100-sec.
