smile shutter with the sony A55 camera

My friend Alyssa is playing with the "Smile Shutter" mode of my new camera.­

The Sony A55 has a mode where the camera detects in real time if there is a smiling face in the picture, and as soon as the camera sees a smile, it automatically takes a photo.­ It is possible to set the "smile sensitivity" to only detect big smiles, or to trigger on small smiles.­ There is also a real-time smile-intensity meter on the LCD display (Alyssa managed to set it to maximum with her irresistible smiles!).­

As you can see, it does work!

I assume that this mode is designed to help people catch the elusive smiles of their todlers :)
