Here’s a high-tech story that is going to put a smile on your face—or at least that’s what the makers of this new gadget are hoping. What kind of gadget are we talking about here? The kind that knows how important a smile can be. Guess the answer yet? It’s a camera! But not just any camera. This little marvel is stubborn. It won’t actually snap the photo until someone in the shot smiles.

Could this be the end of sad face photos in photo albums around the world? It just may be. But how does the camera know when someone is smiling? The answer lies in special software. This software is specially programmed to focus on faces and scan for a change in contrast on the faces. What does this mean? Well, when a person isn’t smiling, their face is all one shade. But teeth are white (or they are if you brush them!), so as soon as someone cracks a grin, the software notices the difference. This is its go-ahead to snap the shot.

Pretty cool—but do you think this camera can be fooled? Most gadgets can, so you never know. And what if you are taking a serious photo of someone? Or what if you are taking a picture of a mountain, which isn’t all that likely to crack a smile? Does that mean the camera will refuse to take the picture? Hmm, let’s hope it has an on/off switch for this function.

What do you think? Will this be the new future trend in cameras? It just may be. At least until we decide we really liked those grumpy family photos after all!
