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.
Av : Aperture priority AE — Set the desired aperture and the camera
selects the correct shutter speed. Use this mode to control depth of field.
Tv : Shutter priority AE — Set the desired shutter speed and the camera
selects the correct aperture. Use this mode to stop motion.
M : Manual mode — Set this mode to use special combinations of the
aperture and shutter speed.
4. Exposure metering mode is automatically set to average/spot
exposure metering before exposure metering is performed.
There are three exposure metering modes: In the A mode the
average brightness in the entire frame is measured with emphasis on
the center of the frame. The brightness at a specific spot in the center
of the frame is metered in the S mode. The A-S mode automatically
switches between these two modes depending on the contrasts in
the picture.
Notice:
When a polarizing filter is used, ensure
that a circular polarizing filter (C-PL) is
used. The correct exposure cannot be
obtained with a normal (linear) polarizing
filter (PL).
