Shutter Priority Auto Exposure
DESCRIPTION
An advanced mode for greater creative
control.
Shutter Priority enables you to select the
shutter speed manually, while the camera
automatically selects the appropriate aperture.
This lets you use a fast shutter speed to
freeze sports action – or a slow shutter
speed to introduce an intentional blur on
moving objects. If you "pan" along with a
moving ice skater, a slow shutter speed
will blur the background. And if you shoot
a waterfall with slow shutter speed, the water
will take on a beautiful, lace-like effect.
Continued on page 40.
Slow shutter speed enables you to blur the background
as you "pan" the camera.
You can also introduce an evocative blur to the subject
with slow shutter speed.
Fast shutter speed freezes the runner and the background.
