Conclusion: To help get better portraits the S3100 has Nikon's Smart portrait system which incorporates Smile Timer, to take the shot when the subject smiles, Blink Proof to warn when someone's eyes are closed in the shot, and Skin Softening which automatically smoothes uneven skin tones.
Summary: The Nikon Coolpix S3100 is a viable option if all you want is a cheap and cheerful compact camera. There are no stand-out features here, but it is affordable, produces reasonable images and is easy to use.
Excerpt: Announced in February 2011, the Coolpix S3100 is aimed at users who want a shirt-pocket-sized camera that makes life simple. So simple, that while there are 18 scene modes to choose from, the S3100 has an Auto Scene Selector mode, so even this decision can be left to the camera.
Excerpt: Not all of us want the bulk associated with a DSLR or the need to buy lenses for our compact system cameras; sometimes all we - or perhaps more accurately our other halves - want to do is take snapshots as a keepsake without spending a king's ransom.
Excerpt: Not just elegant, the design of the Nikon Coolpix S3100 is also comfortable to hold, thanks to a raised grip for your thumb. In operation, it's easy to use with nicely-spaced buttons in a configuration that'll be familiar to most compact users, while the menu system is very slick and easy to navigate. It's pretty responsive, too, with fast write and startup speeds.
