What is this? We bought our son a cheap ($90) point and shoot for Christmas, and it boasts features I've seen on other name brand cameras coming out-face tracking and smile recognition.. It claims that it can detect when someone smiles and capture it. Now this seems a little silly to me, and I was just wondering if anyone has any experience with these seemingly useless features? I mean, if you can't track a face or determine when someone smiles, you probably shouldn't be driving a camera... Anyway, here's the camera in question: http://www.bestbuy.com/site/olspage.jsp?skuId=8942433&type=product&id=1215217299399 And here is the claim: "Face Detection technology Tracks faces within the frame and automatically focuses and optimizes exposure. Smile capture mode automatically releases the shutter to snap a digital photo when your subject smiles."
