Take a look at this YouTube clip showcasing the newly released Sony Cybershot DSC-T200 with “smile shutter“, which takes a picture based on the smiles of the subjects. The software measures and rates the smile on a 0 – 100 percent scale, and takes the picture based on your personal settings. Furthermore, it has the ability to track up to 8 subjects per picture at a time!  You’ll never have to say “cheese” again!
