Pressing the <Q> button enables you to set the following:
(1) Shoot by ambience selection
You can set the ambience you want to convey in your images. Press
the <U> key or turn the <6> dial to select the desired
ambience. You can also select it from a list by pressing <0>. For
details, see the Camera Instruction Manual CD-ROM.
(2) Blurring/sharpening the background
If you move the index mark toward the left, the background will look
more blurred. If you move it toward the right, the background will
look more in focus. If you want to blur the background, see "Shooting
Portraits" on page 49. Press the <U> key or turn the <6> dial to
adjust it as desired.
Depending on the lens and shooting conditions, the background
might not look so blurred. This function cannot be set (grayed out) if
<r> has been set or if the built-in flash is raised with <a> set. If
flash is used, this setting will not be applied.
