Nikon's Scene Auto Selector mode gives the camera the ability to automatically select the correct scene mode for the situation - be it a landscape, portrait, or perhaps a macro photo. When in portrait mode, the Nikon Coolpix S640 also offers both a smile shutter function wherein the camera automatically releases the shutter when the subject of your photo smiles, as well as a blink warning that displays a message on-screen if your subject's eyes weren't open. There's also a skin softening function that offers three different strength levels, and helps conceal blemishes in portrait photos.
