Shooting techniques
• To focus on the smile, overlay the Face Detection frame and AF area.
• Do not cover the eyes with bangs, etc. Keep the eyes narrowed.
• Do not obscure the face with a hat, a mask, sunglasses, etc.
• Try to orient the face in front of the camera and keep it as level as
possible.
• Hold a clear smile with an open mouth. The smile is easier to detect when
the teeth are showing.
• If you press the shutter button while the Smile Shutter function is
activated, the camera shoots the image, and then returns to Smile Shutter.
Notes
• The [Smile Shutter] function cannot be used when the exposure mode is set to
[Sweep Panorama], [Tele-zoom Cont. Priority AE], [Movie], or [Hand-held
Twilight] in [Scene Selection], or when manual focus is selected.
• [Drive Mode] is automatically set to [Single Shooting].
• The AF illuminator does not work with the Smile Shutter function.
• If the camera does not detect a smile, change the settings for Smile Detection
Sensitivity.
• Smiles may not be detected correctly, depending on the shooting conditions.
• If the camera tracks a face using [Lock-on AF] with Smile Shutter turned on, the
face becomes the target of the smile detection feature (page 111).
