A camera that detects when someone smiles and then it triggers the shutter to go off??? That's already old technology.....
Now Sony has a camera that actually will edit your photo to place a 1-5 smile on your subject's face if they aren't smilling. Sony’s frown-fixing tool, which is called Happy Face Retouch, takes already captured images and turns their frowns or ambivalent looks into smiles. Though this was good for laughs, the eerie-looking grins pasted on faces reminded me of painted-on clowns’ mouths, but a handful of the Happy Face Retouches looked somewhat natural.
It was truly hillarious technology.
