Smart Auto mode uses Scene Detection Technology to determine the shooting scene from subject brightness, contrast, distance and hue. The camera selects the appropriate scene from a possible 22, and applies optimal settings. Smart Flash Exposure intelligently adjusts flash for best results while Smart Shutter mode lets you trigger the shot by winking, smiling, or after an extra face enters the frame.
