Sony technology focuses on smiles
"Using the smile recognition shutter function selected by the touch panel, you can pick which of up to eight people is the key smile," said Akira Tokuse who works in Sony product development.
"In a parents-and-baby shot, you could select the baby."
The "Say Cheese" technology has three setting levels, from a slight grin to a belly laugh.
I can see this making child photography easier - just set the camera and concentrate on getting the child to smile - and let the camera take the picture when it's the "right time."
