Shooting
an
image
the
way
you
want
it
(Exposure
mode)
With a single lens reflex camera, you can adjust the shutter speed (how
long the shutter
is
open) and aperture (the range that
is
in
focus: depth
of
field) to enjoy a variety
of
photographic expressions.
For example, you can use a fast shutter speed to shoot the ephemeral shape
of
a wave,
or
you can accentuate a flower by opening the aperture
to
put
everything in front
of
and beyond the flower out
of
focus. These are a few
of
the effects you can enjoy with your camera (pages 59, 61).
Adjusting the shutter speed and aperture not only creates the photographic
effects
of
movement and focus, but also determines the brightness
of
the
image by controlling the amount
of
exposure (the amount
of
light the
camera takes in), which is the most important factor
in
photo shooting.

When using a faster shutter speed, the camera opens the shutter for a
shorter time. This means less time for the camera to take in light, resulting
in a darker picture.
To
take a brighter picture, you can open the aperture
(the hole through which the light passes) to some extent
in
order to adjust
the amount
of
light the camera takes
in
at one time.
The brightness
of
the picture adjusted by the shutter speed and aperture is
called "exposure."
This section will show you how
to
adjust the exposure and enjoy various
photo expressions by the use
of
movement, focus, and light. You can find
out the right way to shoot the image and the subject you like.
