face can’t be obscured – that is, no sunglasses, no hats, or anything else that
would give the image recognition algorithm a hard time. And even if the
camera detects that there is more than one face in the picture, it doesn’t
wait for both faces to smile – only one face will trigger it. (That’s why I
said this feature was great for self-portraits but not necessarily for group
pictures.)
Figure 5-73: The smile shutter is an interesting feature but is easily fooled.
(It triggered all of these pictures!)
Some additional details about this feature you ought to know:
Smile Shutter is also a real energy hog – the camera is constantly on a
high state of alert, analyzing the live view stream and staying on
regardless of what you have Power Save set to.
Invoking Smile shutter automatically activates wide area AF and
single-shot.
It’s not selectable if you’re in Manual Focus mode.
TIP: I haven’t tried this myself, but reader Tim Boyle suggests using Smile
Detection at a party – just put your camera on a tripod, set your lens to
“Wide”, ensure that the battery is fully charged, and let the camera shoot
whatever smiling faces it sees!
