The Party-Shot Automatic Photographer is a mount for Sony cameras to sit on a table and observe smiles and faces. Once a face is recognized and smiles, the mount triggers the camera to take a picture. The camera even tilts and zooms as necessary. Currently the Party-Shot Automatic Photographer only works with the Cybershots TX1 and the WX1. This is a great way to take candid photos. The device costs $150.
