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., ISO 100 or ISO 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.
EXPOSURE
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. 43), 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.
