3.9 Exposure Modes
(P) Program AE
The aperture and shutter speed are determined automatically for
the optimum exposure, according to the ambient light conditions.
This auto mode is best suited for general photography or for novice
photographers, as it leaves the user free to concentrate on framing and
capturing the subject.
Alter the shutter speed and aperture by turning the front and rear dials
while the
P (Program AE) mode is selected.
Program Shift (PH/PL)
The shutter speed and aperture can be altered by turning the front and
rear dials while the
P (Program AE) mode is selected. In order to avoid
blurred images (due to camera shake while releasing the shutter), or
to open the aperture, change to
PH
(high speed). For slower shutter
speeds and wider depth of field, change to PL (low speed). This function
allows these changes to be made quickly.
Notice:
If a correct exposure cannot be
obtained, the shutter speed and
aperture value blink. In such cases, the
pictures can be taken, but they may be
too bright or too dark.
If the shutter speed and aperture
values blink on the main LCD and
in the viewfinder display when the
program line is shifted, the proper
exposure cannot be achieved.
Select a different program mode.
When the Program line is shifted, the
aperture value changes along with the
shutter speed to maintain the proper
exposure.
Increment of the aperture and shutter
speed can be set at either 1/3- or
1/2-stop.
