Nikon Coolpix S550

Nikon Coolpix S550: Digital Photography Review: "Unique new functions for the COOLPIX S550 help make it easier to shoot beautiful portraits and faithfully record precious smiles when they appear. Smile mode displays a gauge that indicates when the selected subject smiles, enabling the user to capture just the right moment. Blink warning displays a message when it detects that a subject has blinked, offers quick magnified visual confirmation, and allows the shot to be retaken immediately."
