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. Changing of picture brightness by the amount of exposure Amount of low high exposure 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. 56

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.
Changing of picture brightness by the amount of exposure
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.
