 The red-eye reduction feature is more effective when the subject looks at
the red-eye reduction lamp, when the room is well lit, or when you are
close to the subject.
 When you press the shutter button halfway, the scale
display on the bottom of the viewfinder will shrink and
turn off. For best results, take the picture after this
scale display turns off.
